■ HANDLING PRECAUTIONS
Any semiconductor devices have inherently a certain rate of failure. The possibility of failure is greatly affected
by the conditions in which they are used (circuit conditions, environmental conditions, etc.). This page
describes precautions that must be observed to minimize the chance of failure and to obtain higher reliability
from your FUJITSU SEMICONDUCTOR semiconductor devices.
1. Precautions for Product Design
This section describes precautions when designing electronic equipment using semiconductor devices.
• Absolute Maximum Ratings
Semiconductor devices can be permanently damaged by application of stress (voltage, current, temperature,
etc.) in excess of certain established limits, called absolute maximum ratings. Do not exceed these ratings.
• Recommended Operating Conditions
Recommended operating conditions are normal operating ranges for the semiconductor device. All the
device's electrical characteristics are warranted when operated within these ranges.
Always use semiconductor devices within the recommended operating conditions. Operation outside these
ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on the data
sheet. Users considering application outside the listed conditions are advised to contact their sales representative beforehand.
• Processing and Protection of Pins
These precautions must be followed when handling the pins which connect semiconductor devices to power
supply and input/output functions.
(1) Preventing Over-Voltage and Over-Current Conditions
Exposure to voltage or current levels in excess of maximum ratings at any pin is likely to cause deterioration within the device, and in extreme cases leads to permanent damage of the device. Try to prevent
such overvoltage or over-current conditions at the design stage.
(2) Protection of Output Pins
Shorting of output pins to supply pins or other output pins, or connection to large capacitance can cause
large current flows. Such conditions if present for extended periods of time can damage the device.
Therefore, avoid this type of connection.
(3) Handling of Unused Input Pins
Unconnected input pins with very high impedance levels can adversely affect stability of operation. Such
pins should be connected through an appropriate resistance to a power supply pin or ground pin.
Code: DS00-00004-2E
DS702–00018–1v0-E
29
MB95710L/770L Series
• Latch-up
Semiconductor devices are constructed by the formation of P-type and N-type areas on a substrate. When
subjected to abnormally high voltages, internal parasitic PNPN junctions (called thyristor structures) may be
formed, causing large current levels in excess of several hundred mA to flow continuously at the power supply
pin. This condition is called latch-up.
CAUTION: The occurrence of latch-up not only causes loss of reliability in the semiconductor device, but
can cause injury or damage from high heat, smoke or flame. To prevent this from happening, do the following:
(1) Be sure that voltages applied to pins do not exceed the absolute maximum ratings. This should
include attention to abnormal noise, surge levels, etc.
(2) Be sure that abnormal current flows do not occur during the power-on sequence.
• Observance of Safety Regulations and Standards
Most countries in the world have established standards and regulations regarding safety, protection from
electromagnetic interference, etc. Customers are requested to observe applicable regulations and standards
in the design of products.
• Fail-Safe Design
Any semiconductor devices have inherently a certain rate of failure. You must protect against injury, damage
or loss from such failures by incorporating safety design measures into your facility and equipment such as
redundancy, fire protection, and prevention of over-current levels and other abnormal operating conditions.
• Precautions Related to Usage of Devices
FUJITSU SEMICONDUCTOR semiconductor devices are intended for use in standard applications (computers, office automation and other office equipment, industrial, communications, and measurement equipment, personal or household devices, etc.).
CAUTION: Customers considering the use of our products in special applications where failure or abnormal
operation may directly affect human lives or cause physical injury or property damage, or where extremely
high levels of reliability are demanded (such as aerospace systems, atomic energy controls, sea floor repeaters, vehicle operating controls, medical devices for life support, etc.) are requested to consult with sales
representatives before such use. The company will not be responsible for damages arising from such use
without prior approval.
2. Precautions for Package Mounting
Package mounting may be either lead insertion type or surface mount type. In either case, for heat resistance
during soldering, you should only mount under FUJITSU SEMICONDUCTOR’s recommended conditions.
For detailed information about mount conditions, contact your sales representative.
• Lead Insertion Type
Mounting of lead insertion type packages onto printed circuit boards may be done by two methods: direct
soldering on the board, or mounting by using a socket.
Direct mounting onto boards normally involves processes for inserting leads into through-holes on the board
and using the flow soldering (wave soldering) method of applying liquid solder. In this case, the soldering
process usually causes leads to be subjected to thermal stress in excess of the absolute ratings for storage
temperature. Mounting processes should conform to FUJITSU SEMICONDUCTOR recommended mounting
conditions.
If socket mounting is used, differences in surface treatment of the socket contacts and IC lead surfaces can
lead to contact deterioration after long periods. For this reason it is recommended that the surface treatment
of socket contacts and IC leads be verified before mounting.
30
DS702–00018–1v0-E
MB95710L/770L Series
• Surface Mount Type
Surface mount packaging has longer and thinner leads than lead-insertion packaging, and therefore leads
are more easily deformed or bent. The use of packages with higher pin counts and narrower pin pitch results
in increased susceptibility to open connections caused by deformed pins, or shorting due to solder bridges.
You must use appropriate mounting techniques. FUJITSU SEMICONDUCTOR recommends the solder
reflow method, and has established a ranking of mounting conditions for each product. Users are advised
to mount packages in accordance with FUJITSU SEMICONDUCTOR ranking of recommended conditions.
• Lead-Free Packaging
CAUTION: When ball grid array (BGA) packages with Sn-Ag-Cu balls are mounted using Sn-Pb eutectic
soldering, junction strength may be reduced under some conditions of use.
• Storage of Semiconductor Devices
Because plastic chip packages are formed from plastic resins, exposure to natural environmental conditions
will cause absorption of moisture. During mounting, the application of heat to a package that has absorbed
moisture can cause surfaces to peel, reducing moisture resistance and causing packages to crack. To
prevent, do the following:
(1) Avoid exposure to rapid temperature changes, which cause moisture to condense inside the product.
Store products in locations where temperature changes are slight.
(2) Use dry boxes for product storage. Products should be stored below 70% relative humidity, and at
temperatures between 5 °C and 30 °C.
When you open Dry Package that recommends humidity 40% to 70% relative humidity.
(3) When necessary, FUJITSU SEMICONDUCTOR packages semiconductor devices in highly moistureresistant aluminum laminate bags, with a silica gel desiccant. Devices should be sealed in their aluminum
laminate bags for storage.
(4) Avoid storing packages where they are exposed to corrosive gases or high levels of dust.
• Baking
Packages that have absorbed moisture may be de-moisturized by baking (heat drying). Follow the FUJITSU
SEMICONDUCTOR recommended conditions for baking.
Condition: 125 °C/24 h
• Static Electricity
Because semiconductor devices are particularly susceptible to damage by static electricity, you must take
the following precautions:
(1) Maintain relative humidity in the working environment between 40% and 70%.
Use of an apparatus for ion generation may be needed to remove electricity.
(2) Electrically ground all conveyors, solder vessels, soldering irons and peripheral equipment.
(3) Eliminate static body electricity by the use of rings or bracelets connected to ground through high resistance (on the level of 1 MΩ).
Wearing of conductive clothing and shoes, use of conductive floor mats and other measures to minimize
shock loads is recommended.
(4) Ground all fixtures and instruments, or protect with anti-static measures.
(5) Avoid the use of styrofoam or other highly static-prone materials for storage of completed board assemblies.

MB95710L/770L Series
3. Precautions for Use Environment
Reliability of semiconductor devices depends on ambient temperature and other conditions as described
above.
For reliable performance, do the following:
(1) Humidity
Prolonged use in high humidity can lead to leakage in devices as well as printed circuit boards. If high
humidity levels are anticipated, consider anti-humidity processing.
(2) Discharge of Static Electricity
When high-voltage charges exist close to semiconductor devices, discharges can cause abnormal
operation. In such cases, use anti-static measures or processing to prevent discharges.
(3) Corrosive Gases, Dust, or Oil
Exposure to corrosive gases or contact with dust or oil may lead to chemical reactions that will adversely
affect the device. If you use devices in such conditions, consider ways to prevent such exposure or to
protect the devices.
(4) Radiation, Including Cosmic Radiation
Most devices are not designed for environments involving exposure to radiation or cosmic radiation.
Users should provide shielding as appropriate.
(5) Smoke, Flame
CAUTION: Plastic molded devices are flammable, and therefore should not be used near combustible
substances. If devices begin to smoke or burn, there is danger of the release of toxic gases.
Customers considering the use of FUJITSU SEMICONDUCTOR products in other special environmental
conditions should consult with sales representatives.

■ NOTES ON DEVICE HANDLING
• Preventing latch-ups
When using the device, ensure that the voltage applied does not exceed the maximum voltage rating.
In a CMOS IC, if a voltage higher than VCC or a voltage lower than VSS is applied to an input/output pin that
is neither a medium-withstand voltage pin nor a high-withstand voltage pin, or if a voltage out of the rating
range of power supply voltage mentioned in “1. Absolute Maximum Ratings” of “■ ELECTRICAL CHARACTERISTICS” is applied to the VCC pin or the VSS pin, a latch-up may occur.
When a latch-up occurs, power supply current increases significantly, which may cause a component to be
thermally destroyed.
• Stabilizing supply voltage
Supply voltage must be stabilized.
A malfunction may occur when power supply voltage fluctuates rapidly even though the fluctuation is within
the guaranteed operating range of the VCC power supply voltage.
As a rule of voltage stabilization, suppress voltage fluctuation so that the fluctuation in VCC ripple (p-p value)
at the commercial frequency (50 Hz/60 Hz) does not exceed 10% of the standard VCC value, and the transient fluctuation rate does not exceed 0.1 V/ms at a momentary fluctuation such as switching the power supply.
• Notes on using the external clock
When an external clock is used, oscillation stabilization wait time is required for power-on reset, wake-up
from subclock mode or stop mode.
■ PIN CONNECTION
• Treatment of unused pins
If an unused input pin is left unconnected, a component may be permanently damaged due to malfunctions
or latch-ups. Always pull up or pull down an unused input pin through a resistor of at least 2 kΩ. Set an unused input/output pin to the output state and leave it unconnected, or set it to the input state and treat it the
same as an unused input pin. If there is an unused output pin, leave it unconnected.
• Power supply pins
To reduce unnecessary electro-magnetic emission, prevent malfunctions of strobe signals due to an increase in the ground level, and conform to the total output current standard, always connect the VCC pin and
the VSS pin to the power supply and ground outside the device. In addition, connect the current supply
source to the VCC pin and the VSS pin with low impedance.
It is also advisable to connect a ceramic capacitor of approximately 1.0 µF as a bypass capacitor between
the VCC pin and the VSS pin at a location close to this device.
• DBG pin
Connect the DBG pin to an external pull-up resistor of 2 kΩ or above.
After power-on, ensure that the DBG pin does not stay at “L” level until the reset output is released.
The DBG pin becomes a communication pin in debug mode. Since the actual pull-up resistance depends
on the tool used and the interconnection length, refer to the tool document when selecting a pull-up resistor.
• RST pin
Connect the RST pin to an external pull-up resistor of 2 kΩ or above.
To prevent the device from unintentionally entering the reset mode due to noise, minimize the interconnection length between a pull-up resistor and the RST pin and that between a pull-up resistor and the VCC pin
when designing the layout of the printed circuit board.
The PF2/RST pin functions as the reset input/output pin after power-on. In addition, the reset output of the
PF2/RST pin can be enabled by the RSTOE bit in the SYSC register, and the reset input function and the
general-purpose I/O function can be selected by the RSTEN bit in the SYSC register.
• Analog power supply
Always set the same potential to the AVCC pin and the VCC pin. When VCC is larger than AVCC, the current
may flow through the AN00 to AN07 pins.
DS702–00018–1v0-E
33
MB95710L/770L Series
• Treatment of power supply pins on the 8/12-bit A/D converter
Ensure that AVCC is equal to VCC and AVSS equal to VSS even when the 8/12-bit A/D converter is not in use.
Noise riding on the AVCC pin may cause accuracy degradation. Therefore, connect a ceramic capacitor of
0.1 µF (approx.) as a bypass capacitor between the AVCC pin and the AVSS pin in the vicinity of this device.
• C pin
Use a ceramic capacitor or a capacitor with equivalent frequency characteristics. The decoupling capacitor
for the VCC pin must have a capacitance equal to or larger than the capacitance of CS. For the connection
to a decoupling capacitor CS, see the diagram below. To prevent the device from unintentionally entering a
mode to which the device is not set to transit due to noise, minimize the distance between the C pin and CS
and the distance between CS and the VSS pin when designing the layout of a printed circuit board.

• Note on serial communication
In serial communication, reception of wrong data may occur due to noise or other causes. Therefore, design
a printed circuit board to prevent noise from occurring. Taking account of the reception of wrong data, take
measures such as adding a checksum to the end of data in order to detect errors. If an error is detected,
retransmit the data.

■ MEMORY SPACE
The memory space of the MB95710L/770L Series is 64 Kbyte in size, and consists of an I/O area, an extended I/O area, a data area, and a program area. The memory space includes areas for specific applications such as general-purpose registers and a vector table.
• I/O area (addresses: 0x0000 to 0x007F)
• This area contains the control registers and data registers for built-in peripheral functions.
• As the I/O area forms part of the memory space, it can be accessed in the same way as the memory. It
can also be accessed at high-speed by using direct addressing instructions.
• Extended I/O area (addresses: 0x0F80 to 0x0FFF)
• This area contains the control registers and data registers for built-in peripheral functions.
• As the extended I/O area forms part of the memory space, it can be accessed in the same way as the
memory.
• Data area
• Static RAM is incorporated in the data area as the internal data area.
• The internal RAM size varies according to product.
• The RAM area from 0x0090 to 0x00FF can be accessed at high-speed by using direct addressing instructions.
• In MB95F716E/F716L/F718E/F718L/F776E/F776L/F778E/F778L, the area from 0x0090 to 0x047F is an
extended direct addressing area. It can be accessed at high-speed by direct addressing instructions with
a direct bank pointer set.
• In MB95F714E/F714L/F774E/F774L, the area from 0x0090 to 0x028F is an extended direct addressing
area. It can be accessed at high-speed by direct addressing instructions with a direct bank pointer set.
• The area from 0x0100 to 0x01FF can be used as a general-purpose register area.
• Program area
• The Flash memory is incorporated in the program area as the internal program area.
• The Flash memory size varies according to product.
• The area from 0xFFC0 to 0xFFFF is used as the vector table.
• The area from 0xFFBB to 0xFFBF is used to store data of the non-volatile register.

■ AREAS FOR SPECIFIC APPLICATIONS
The general-purpose register area and vector table area are used for the specific applications.
• General-purpose register area (Addresses: 0x0100 to 0x01FF)
• This area contains the auxiliary registers used for 8-bit arithmetic operations, transfer, etc.
• As this area forms part of the RAM area, it can also be used as conventional RAM.
• When the area is used as general-purpose registers, general-purpose register addressing enables highspeed access with short instructions.
• Non-volatile register data area (Addresses: 0xFFBB to 0xFFBF)
• The area from 0xFFBB to 0xFFBF is used to store data of the non-volatile register. For details, refer to
“CHAPTER 28 NON-VOLATILE REGISTER (NVR) INTERFACE” in “New 8FX MB95710L/770L Series
Hardware Manual”
• Vector table area (Addresses: 0xFFC0 to 0xFFFF)
• This area is used as the vector table for vector call instructions (CALLV), interrupts, and resets.
• The top of the Flash memory area is allocated to the vector table area. The start address of a service
routine is set to an address in the vector table in the form of data.
“■ INTERRUPT SOURCE TABLE” lists the vector table addresses corresponding to vector call instructions,
interrupts, and resets.
For details, refer to “CHAPTER 4 RESET”, “CHAPTER 5 INTERRUPTS”, and “A.2 Special Instruction
■ Special Instruction ● CALLV #vct” in “APPENDIX” in “New 8FX MB95710L/770L Series Hardware Manual”.

(4) Port 0 operations
• Operation as an output port
• A pin becomes an output port if the bit in the DDR0 register corresponding to that pin is set to “1”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• When a pin is used as an output port, it outputs the value of the PDR0 register to external pins.
• If data is written to the PDR0 register, the value is stored in the output latch and is output to the pin set as
an output port as it is.
• Reading the PDR0 register returns the PDR0 register value.
• To use a pin shared with the LCDC as an output port, set a corresponding function select bit in the LCDC
enable register 6 (LCDCE6:SEG[31:30]) or in the LCDC enable register 7 (LCDCE7:SEG[36:32]) to “0” to
select the general-purpose I/O port function, and then set the port input control bit in the LCDC enable
register 1 (LCDCE1:PICTL) to “1”.
• Operation as an input port
• A pin becomes an input port if the bit in the DDR0 register corresponding to that pin is set to “0”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• When using an analog input shared pin as an input port, set the corresponding bit in the A/D input disable
register (lower) (AIDRL) to “1”.
• If data is written to the PDR0 register, the value is stored in the output latch but is not output to the pin set
as an input port.
• Reading the PDR0 register returns the pin value. However, if the read-modify-write (RMW) type of instruction is used to read the PDR0 register, the PDR0 register value is returned.
• To use a pin shared with the LCDC as an input port, set a corresponding function select bit in the LCDC
enable register 6 (LCDCE6:SEG[31:30]) or in the LCDC enable register 7 (LCDCE7:SEG[36:32]) to “0” to
select the general-purpose I/O port function, and then set the PICTL bit in the LCDCE1 register to “1”.
• Operation as a peripheral function output pin
• A pin becomes a peripheral function output pin if the peripheral output function is enabled by setting the
output enable bit of a peripheral function corresponding to that pin.
• The pin value can be read from the PDR0 register even if the peripheral function output is enabled. Therefore, the output value of a peripheral function can be read by the read operation on the PDR0 register.
However, if the read-modify-write (RMW) type of instruction is used to read the PDR0 register, the PDR0
register value is returned.
• Operation as a peripheral function input pin
• To set a pin as an input port, set the bit in the DDR0 register corresponding to the input pin of a peripheral
function to “0”.
• When using the analog input shared pin as another peripheral function input pin, configure it as an input
port, which is the same as the operation as an input port.
• Reading the PDR0 register returns the pin value, regardless of whether the peripheral function uses that
pin as its input pin. However, if the read-modify-write (RMW) type of instruction is used to read the PDR0
register, the PDR0 register value is returned.
• Operation as an LCDC segment output pin
• Set the bit in the DDR0 register corresponding to an LCDC segment output pin to “0”.
• To use a pin shared with a general-purpose I/O port as an LCDC segment output pin, set a corresponding
function select bit in the LCDC enable register 6 (LCDCE6:SEG[31:30]) or in the LCDC enable register 7
(LCDCE7:SEG[36:32]) to “1” to select the LCDC segment output function, and then set the PICTL bit in
the LCDCE1 register to “1”.
• Operation at reset
If the CPU is reset, all bits in the DDR0 register are initialized to “0” and port input is enabled. As for a pin
shared with analog input, its port input is disabled because the AIDRL register is initialized to “0”.
58
DS702–00018–1v0-E
MB95710L/770L Series
• Operation in stop mode and watch mode
• If the pin state setting bit in the standby control register (STBC:SPL) is set to “1” and the device transits
to stop mode or watch mode, the pin is compulsorily made to enter the high impedance state regardless
of the DDR0 register value. The input of that pin is locked to “L” level and blocked in order to prevent leaks
due to input open. However, if the interrupt input is enabled for the external interrupt (INT00 to INT07), the
input is enabled and not blocked.
• If the pin state setting bit is “0”, the state of the port I/O or that of the peripheral function I/O remains unchanged and the output level is maintained.
• Operation as an analog input pin
• Set the bit in the DDR0 register bit corresponding to the analog input pin to “0” and the bit corresponding
to that pin in the AIDRL register to “0”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• Operation as an external interrupt input pin
• Set the bit in the DDR0 register corresponding to the external interrupt input pin to “0”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• The pin value is always input to the external interrupt circuit. When using a pin for a function other than
the interrupt, disable the external interrupt function corresponding to that pin.

• Operation as a peripheral function output pin
• A pin becomes a peripheral function output pin if the peripheral output function is enabled by setting the

• The pin value can be read from the PDR1 register even if the peripheral function output is enabled. Therefore, the output value of a peripheral function can be read by the read operation on the PDR1 register.
However, if the read-modify-write (RMW) type of instruction is used to read the PDR1 register, the PDR1

due to input open. However, if the interrupt input of P10/UI0 and P14/UCK0 is enabled by the external
interrupt control register ch. 0 (EIC00) of the external interrupt circuit and the interrupt pin selection circuit
control register (WICR) of the interrupt pin selection circuit, the input is enabled and is not blocked.
• If the pin state setting bit is “0”, the state of the port I/O or that of the peripheral function I/O remains unchanged and the output level is maintained.
• Operation of the pull-up register
Setting the bit in the PUL1 register to “1” makes the pull-up resistor be internally connected to the pin. When
the pin output is “L” level, the pull-up resistor is disconnected regardless of the value of the PUL1 register.

(4) Port 2 operations
• Operation as an output port
• A pin becomes an output port if the bit in the DDR2 register corresponding to that pin is set to “1”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• When a pin is used as an output port, it outputs the value of the PDR2 register to external pins.
• If data is written to the PDR2 register, the value is stored in the output latch and is output to the pin set as
an output port as it is.
• Reading the PDR2 register returns the PDR2 register value.
• Operation as an input port
• A pin becomes an input port if the bit in the DDR2 register corresponding to that pin is set to “0”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• If data is written to the PDR2 register, the value is stored in the output latch but is not output to the pin set
as an input port.
• Reading the PDR2 register returns the pin value. However, if the read-modify-write (RMW) type of instruction is used to read the PDR2 register, the PDR2 register value is returned.
• Operation as a peripheral function output pin
• A pin becomes a peripheral function output pin if the peripheral output function is enabled by setting the
output enable bit of a peripheral function corresponding to that pin.
• The pin value can be read from the PDR2 register even if the peripheral function output is enabled. Therefore, the output value of a peripheral function can be read by the read operation on the PDR2 register.
However, if the read-modify-write (RMW) type of instruction is used to read the PDR2 register, the PDR2
register value is returned.
• Operation as a peripheral function input pin
• To set a pin as an input port, set the bit in the DDR2 register corresponding to the input pin of a peripheral
function to “0”.
• Reading the PDR2 register returns the pin value, regardless of whether the peripheral function uses that
pin as its input pin. However, if the read-modify-write (RMW) type of instruction is used to read the PDR2
register, the PDR2 register value is returned.
• Operation at reset
If the CPU is reset, all bits in the DDR2 register are initialized to “0” and port input is enabled.
• Operation in stop mode and watch mode
• If the pin state setting bit in the standby control register (STBC:SPL) is set to “1” and the device transits
to stop mode or watch mode, the pin is compulsorily made to enter the high impedance state regardless
of the DDR2 register value. The input of that pin is locked to “L” level and blocked in order to prevent leaks
due to input open.
• If the pin state setting bit is “0”, the state of the port I/O or that of the peripheral function I/O remains unchanged and the output level is maintained.
• Operation of the pull-up register
Setting the bit in the PUL2 register to “1” makes the pull-up resistor be internally connected to the pin. When
the pin output is “L” level, the pull-up resistor is disconnected regardless of the value of the PUL2 register.
• Operation as a comparator input pin
• Regardless of the value of the PDR2 register and that of the DDR2 register, if the comparator analog input
enable bit in the comparator control register ch. 0 (CMR0:VCID) is set to “0”, the comparator input function
is enabled.
• To disable the comparator input function, set the VCID bit to “1”.
• For details of the comparator, refer to “CHAPTER 29 COMPARATOR” in “New 8FX MB95710L/770L Series Hardware Manual”.

If the CPU is reset, all bits in the DDR9 register are initialized to “0” and port input is enabled.
• Operation in stop mode and watch mode
• If the pin state setting bit in the standby control register (STBC:SPL) is set to “1” and the device transits
to stop mode or watch mode, the pin is compulsorily made to enter the high impedance state regardless
of the DDR9 register value. The input of that pin is locked to “L” level and blocked in order to prevent leaks
due to input open.
• If the pin state setting bit is “0”, the state of the port I/O or that of the peripheral function I/O remains unchanged and the output level is maintained.
• Operation as an LCD drive power supply pin
• Set the bit in the DDR9 register corresponding to an LCD drive power supply pin to “0”.
• To use a pin shared with a general-purpose I/O port as an LCD drive power supply pin, set the bit corresponding to that pin in the VE[4:0] bits in the LCDCE1 register to “1” to select the LCD drive power supply
function.

• To use a pin shared with the LCDC as an output port, set a corresponding function select bit in the LCDC
enable register 5 (LCDCE5:SEG[23:22]) or in the LCDC enable register 6 (LCDCE6:SEG[29:24]) to “0” to
select the general-purpose I/O port function, and then set the port input control bit in the LCDC enable
register 1 (LCDCE1:PICTL) to “1”.
• Operation as an input port
• A pin becomes an input port if the bit in the DDRE register corresponding to that pin is set to “0”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• If data is written to the PDRE register, the value is stored in the output latch but is not output to the pin set

select the general-purpose I/O port function, and then set the PICTL bit in the LCDCE1 register to “1”.
• Operation as a peripheral function output pin
• A pin becomes a peripheral function output pin if the peripheral output function is enabled by setting the
output enable bit of a peripheral function corresponding to that pin.
• The pin value can be read from the PDRE register even if the peripheral function output is enabled. Therefore, the output value of a peripheral function can be read by the read operation on the PDRE register.
However, if the read-modify-write (RMW) type of instruction is used to read the PDRE register, the PDRE
register value is returned.
• Operation as a peripheral function input pin
• To set a pin as an input port, set the bit in the DDRE register corresponding to the input pin of a peripheral
function to “0”.
• Reading the PDRE register returns the pin value, regardless of whether the peripheral function uses that
pin as its input pin. However, if the read-modify-write (RMW) type of instruction is used to read the PDRE
register, the PDRE register value is returned.
• Operation as an LCDC segment output pin
• Set the bit in the DDRE register corresponding to an LCDC segment output pin to “0”.
• To use a pin shared with a general-purpose I/O port as an LCDC segment output pin, set a corresponding
function select bit in the LCDC enable register 5 (LCDCE5:SEG[23:22]) or in the LCDC enable register 6
(LCDCE6:SEG[29:24]) to “1” to select the LCDC segment output function, and then set the PICTL bit in
the LCDCE1 register to “1”.
• Operation at reset
If the CPU is reset, all bits in the DDRE register are initialized to “0” and port input is enabled.
• Operation in stop mode and watch mode
• If the pin state setting bit in the standby control register (STBC:SPL) is set to “1” and the device transits
to stop mode or watch mode, the pin is compulsorily made to enter the high impedance state regardless
of the DDRE register value. The input of that pin is locked to “L” level and blocked in order to prevent leaks
due to input open.
• If the pin state setting bit is “0”, the state of the port I/O or that of the peripheral function I/O remains unchanged and the output level is maintained.

(4) Port F operations
• Operation as an output port
• A pin becomes an output port if the bit in the DDRF register corresponding to that pin is set to “1”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• When a pin is used as an output port, it outputs the value of the PDRF register to external pins.
• If data is written to the PDRF register, the value is stored in the output latch and is output to the pin set as
an output port as it is.
• Reading the PDRF register returns the PDRF register value.
• Operation as an input port
• A pin becomes an input port if the bit in the DDRF register corresponding to that pin is set to “0”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• If data is written to the PDRF register, the value is stored in the output latch but is not output to the pin set
as an input port.
• Reading the PDRF register returns the pin value. However, if the read-modify-write (RMW) type of instruction is used to read the PDRF register, the PDRF register value is returned.
• Operation at reset
If the CPU is reset, all bits in the DDRF register are initialized to “0” and port input is enabled.
• Operation in stop mode and watch mode
• If the pin state setting bit in the standby control register (STBC:SPL) is set to “1” and the device transits
to stop mode or watch mode, the pin is compulsorily made to enter the high impedance state regardless
of the DDRF register value. The input of that pin is locked to “L” level and blocked in order to prevent leaks
due to input open.
• If the pin state setting bit is “0”, the state of the port I/O or that of the peripheral function I/O remains unchanged and the output level is maintained.

(4) Port 0 operations
• Operation as an output port
• A pin becomes an output port if the bit in the DDR0 register corresponding to that pin is set to “1”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• When a pin is used as an output port, it outputs the value of the PDR0 register to external pins.
• If data is written to the PDR0 register, the value is stored in the output latch and is output to the pin set as
an output port as it is.
• Reading the PDR0 register returns the PDR0 register value.
• To use a pin shared with the LCDC as an output port, set a corresponding function select bit in the LCDC
enable register 5 (LCDCE5:SEG[23:22]) or in the LCDC enable register 6 (LCDCE6:SEG[29:24]) to “0” to
select the general-purpose I/O port function, and then set the port input control bit in the LCDC enable
register 1 (LCDCE1:PICTL) to “1”.
• Operation as an input port
• A pin becomes an input port if the bit in the DDR0 register corresponding to that pin is set to “0”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• When using an analog input shared pin as an input port, set the corresponding bit in the A/D input disable
register (lower) (AIDRL) to “1”.
• If data is written to the PDR0 register, the value is stored in the output latch but is not output to the pin set
as an input port.
• Reading the PDR0 register returns the pin value. However, if the read-modify-write (RMW) type of instruction is used to read the PDR0 register, the PDR0 register value is returned.
• To use a pin shared with the LCDC as an input port, set a corresponding function select bit in the LCDC
enable register 5 (LCDCE5:SEG[23:22]) or in the LCDC enable register 6 (LCDCE6:SEG[29:24]) to “0” to
select the general-purpose I/O port function, and then set the PICTL bit in the LCDCE1 register to “1”.
• Operation as a peripheral function output pin
• A pin becomes a peripheral function output pin if the peripheral output function is enabled by setting the
output enable bit of a peripheral function corresponding to that pin.
• The pin value can be read from the PDR0 register even if the peripheral function output is enabled. Therefore, the output value of a peripheral function can be read by the read operation on the PDR0 register.
However, if the read-modify-write (RMW) type of instruction is used to read the PDR0 register, the PDR0
register value is returned.
• Operation as a peripheral function input pin
• To set a pin as an input port, set the bit in the DDR0 register corresponding to the input pin of a peripheral
function to “0”.
• When using the analog input shared pin as another peripheral function input pin, configure it as an input
port, which is the same as the operation as an input port.
• Reading the PDR0 register returns the pin value, regardless of whether the peripheral function uses that
pin as its input pin. However, if the read-modify-write (RMW) type of instruction is used to read the PDR0
register, the PDR0 register value is returned.
• Operation as an LCDC segment output pin
• Set the bit in the DDR0 register corresponding to an LCDC segment output pin to “0”.
• To use a pin shared with a general-purpose I/O port as an LCDC segment output pin, set a corresponding
function select bit in the LCDC enable register 5 (LCDCE5:SEG[23:22]) or in the LCDC enable register 6
(LCDCE6:SEG[29:24]) to “1” to select the LCDC segment output function, and then set the PICTL bit in
the LCDCE1 register to “1”.
• Operation at reset
If the CPU is reset, all bits in the DDR0 register are initialized to “0” and port input is enabled. As for a pin
shared with analog input, its port input is disabled because the AIDRL register is initialized to “0”.
110
DS702–00018–1v0-E
MB95710L/770L Series
• Operation in stop mode and watch mode
• If the pin state setting bit in the standby control register (STBC:SPL) is set to “1” and the device transits
to stop mode or watch mode, the pin is compulsorily made to enter the high impedance state regardless
of the DDR0 register value. The input of that pin is locked to “L” level and blocked in order to prevent leaks
due to input open. However, if the interrupt input is enabled for the external interrupt (INT00 to INT07), the
input is enabled and not blocked.
• If the pin state setting bit is “0”, the state of the port I/O or that of the peripheral function I/O remains unchanged and the output level is maintained.
• Operation as an analog input pin
• Set the bit in the DDR0 register bit corresponding to the analog input pin to “0” and the bit corresponding
to that pin in the AIDRL register to “0”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• Operation as an external interrupt input pin
• Set the bit in the DDR0 register corresponding to the external interrupt input pin to “0”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• The pin value is always input to the external interrupt circuit. When using a pin for a function other than
the interrupt, disable the external interrupt function corresponding to that pin.

• The pin value can be read from the PDR1 register even if the peripheral function output is enabled. Therefore, the output value of a peripheral function can be read by the read operation on the PDR1 register.
However, if the read-modify-write (RMW) type of instruction is used to read the PDR1 register, the PDR1
register value is returned.
• Operation as a peripheral function input pin
• To set a pin as an input port, set the bit in the DDR1 register corresponding to the input pin of a peripheral
function to “0”.
• Reading the PDR1 register returns the pin value, regardless of whether the peripheral function uses that
pin as its input pin. However, if the read-modify-write (RMW) type of instruction is used to read the PDR1
register, the PDR1 register value is returned.
• Operation as an LCDC segment output pin
• Set the bit in the DDR1 register corresponding to an LCDC segment output pin to “0”.
• To use a pin shared with a general-purpose I/O port as an LCDC segment output pin, set a corresponding
function select bit in the LCDC enable register 6 (LCDCE6:SEG[31:30]) to “1” to select the LCDC segment
output function, and then set the PICTL bit in the LCDCE1 register to “1”.
• Operation at reset
If the CPU is reset, all bits in the DDR1 register are initialized to “0” and port input is enabled.

• Operation in stop mode and watch mode
• If the pin state setting bit in the standby control register (STBC:SPL) is set to “1” and the device transits
to stop mode or watch mode, the pin is compulsorily made to enter the high impedance state regardless
of the DDR1 register value. The input of that pin is locked to “L” level and blocked in order to prevent leaks
due to input open. However, if the interrupt input of P10/UI0/TO0 and P14/UCK0/EC0/TI0 is enabled by
the external interrupt control register ch. 0 (EIC00) of the external interrupt circuit and the interrupt pin
selection circuit control register (WICR) of the interrupt pin selection circuit, the input is enabled and is not
blocked.
• If the pin state setting bit is “0”, the state of the port I/O or that of the peripheral function I/O remains unchanged and the output level is maintained.
• Operation of the pull-up register
Setting the bit in the PUL1 register to “1” makes the pull-up resistor be internally connected to the pin. When
the pin output is “L” level, the pull-up resistor is disconnected regardless of the value of the PUL1 register.

• A pin becomes an output port if the bit in the DDRB register corresponding to that pin is set to “1”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• When a pin is used as an output port, it outputs the value of the PDRB register to external pins.
• If data is written to the PDRB register, the value is stored in the output latch and is output to the pin set as
an output port as it is.
• Reading the PDRB register returns the PDRB register value.
• To use a pin shared with the LCDC as an output port, set a corresponding function select bit in the LCDC
enable register 3 (LCDCE3:SEG[01:00]) to “0” to select the general-purpose I/O port function, and then
set the port input control bit in the LCDC enable register 1 (LCDCE1:PICTL) to “1”.
• Operation as an input port
• A pin becomes an input port if the bit in the DDRB register corresponding to that pin is set to “0”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• If data is written to the PDRB register, the value is stored in the output latch but is not output to the pin set
as an input port.
• Reading the PDRB register returns the pin value. However, if the read-modify-write (RMW) type of instruction is used to read the PDRB register, the PDRB register value is returned.
• To use a pin shared with the LCDC as an input port, set a corresponding function select bit in the LCDC
enable register 3 (LCDCE3:SEG[01:00]) to “0” to select the general-purpose I/O port function, and then
set the PICTL bit in the LCDCE1 register to “1”.
• Operation as an LCDC segment output pin
• Set the bit in the DDRB register corresponding to an LCDC segment output pin to “0”.
• To use a pin shared with a general-purpose I/O port as an LCDC segment output pin, set a corresponding
function select bit in the LCDC enable register 3 (LCDCE3:SEG[01:00]) to “1” to select the LCDC segment
output function, and then set the PICTL bit in the LCDCE1 register to “1”.
• Operation at reset
If the CPU is reset, all bits in the DDRB register are initialized to “0” and port input is enabled.
• Operation in stop mode and watch mode
• If the pin state setting bit in the standby control register (STBC:SPL) is set to “1” and the device transits
to stop mode or watch mode, the pin is compulsorily made to enter the high impedance state regardless
of the DDRB register value. The input of that pin is locked to “L” level and blocked in order to prevent leaks
due to input open.
• If the pin state setting bit is “0”, the state of the port I/O or that of the peripheral function I/O remains unchanged and the output level is maintained.

enable register 4 (LCDCE4:SEG[15:14]) or in the LCDC enable register 5 (LCDCE5:SEG[21:16]) to “0” to
select the general-purpose I/O port function, and then set the port input control bit in the LCDC enable
register 1 (LCDCE1:PICTL) to “1”.
• Operation as an input port
• A pin becomes an input port if the bit in the DDRE register corresponding to that pin is set to “0”.
• For a pin shared with other peripheral functions, disable the output of such peripheral functions.
• If data is written to the PDRE register, the value is stored in the output latch but is not output to the pin set

• Operation as a peripheral function output pin
• A pin becomes a peripheral function output pin if the peripheral output function is enabled by setting the
output enable bit of a peripheral function corresponding to that pin.
• The pin value can be read from the PDRE register even if the peripheral function output is enabled. Therefore, the output value of a peripheral function can be read by the read operation on the PDRE register.
However, if the read-modify-write (RMW) type of instruction is used to read the PDRE register, the PDRE
register value is returned.

pin as its input pin. However, if the read-modify-write (RMW) type of instruction is used to read the PDRE
register, the PDRE register value is returned.
• Operation as an LCDC segment output pin
• Set the bit in the DDRE register corresponding to an LCDC segment output pin to “0”.
• To use a pin shared with a general-purpose I/O port as an LCDC segment output pin, set a corresponding

*1: PF0/X0 and PF1/X1 transit to this state on a reset when configured as a main clock oscillation pins.
*2: The pin stays at the state shown when configured as a general-purpose I/O port.
*3: “Input blocked” means direct input gate operation from the pin is disabled.
*4: “Input enabled” means that the input function is enabled. While the input function is enabled, execute a
pull-up or pull-down operation to prevent leaks due to external input. If a pin is used as an output port, its
pin state is the same as that of other ports.
*5: The PF2/RST pin stays at the state shown when configured as a reset pin.
*6: PG1/X0A and PG2/X1A transit to this state on a reset when configured as subclock oscillation pins.
*7: The pull-up control setting is still effective.

*1: These parameters are based on the condition that VSS is 0.0 V.
*2: V1 and V0 must not exceed VCC + 0.3 V. V1 must not exceed the rated voltage. However, if the maximum
current to/from an input is limited by means of an external component, the ICLAMP rating is used instead of
the VI rating.

• Use under recommended operating conditions.
• Use with DC voltage (current).
• The HV (High Voltage) signal is an input signal exceeding the VCC voltage. Always connect a limiting resistor
between the HV (High Voltage) signal and the microcontroller before applying the HV (High Voltage) signal.
• The value of the limiting resistor should be set to a value at which the current to be input to the microcontroller
pin when the HV (High Voltage) signal is input is below the standard value, irrespective of whether the
current is transient current or stationary current.
• When the microcontroller drive current is low, such as in low power consumption modes, the HV (High
Voltage) input potential may pass through the protective diode to increase the potential of the VCC pin,
affecting other devices.
• If the HV (High Voltage) signal is input when the microcontroller power supply is off (not fixed at 0 V), since
power is supplied from the pins, incomplete operations may be executed.
• If the HV (High Voltage) input is input after power-on, since power is supplied from the pins, the voltage
of power supply may not be sufficient to enable a power-on reset.
• Do not leave the HV (High Voltage) input pin unconnected.
• Example of a recommended circuit:
• Input/Output equivalent circuit

WARNING: Semiconductor devices may be permanently damaged by application of stress (including, without
limitation, voltage, current or temperature) in excess of absolute maximum ratings.
Do not exceed any of these ratings.

*1: The minimum power supply voltage becomes 2.18 V when a product with the low-voltage detection reset is
used or when the on-chip debug mode is used.
*2: Use a ceramic capacitor or a capacitor with equivalent frequency characteristics. For the connection to a
decoupling capacitor CS, see the diagram below. To prevent the device from unintentionally entering an unknown mode due to noise, minimize the distance between the C pin and CS and the distance between CS
and the VSS pin when designing the layout of a printed circuit board.

*: Connect the DBG pin to an external pull-up resistor of 2 kΩ or above. After power-on, ensure that the
DBG pin does not stay at “L” level until the reset output is released. The DBG pin becomes a communication pin in debug mode. Since the actual pull-up resistance depends on the tool used and the interconnection length, refer to the tool document when selecting a pull-up resistor.
WARNING: The recommended operating conditions are required in order to ensure the normal operation of
the semiconductor device. All of the device's electrical characteristics are warranted when the
device is operated under these conditions.
Any use of semiconductor devices will be under their recommended operating condition.
Operation under any conditions other than these conditions may adversely affect reliability of
device and could result in device failure.
No warranty is made with respect to any use, operating conditions or combinations not represented
on this data sheet. If you are considering application under any conditions other than listed herein,
please contact sales representatives beforehand.

*2: P40 to P43, P50 to P53, P94, PB2 to PB4 are only available on the MB95710L Series.
*3: When VCC is smaller than 4.5 V, the condition becomes IOH = −2 mA.
*4: When VCC is smaller than 4.5 V, the condition becomes IOL = 2 mA.
*5: VCC = 3.3 V, TA = +85 °C (unless otherwise specified)
*6: • The power supply current is determined by the external clock. When the low-voltage detection reset circuit
is selected, the power supply current is the sum of adding the current consumption of the low-voltage detection reset circuit (IPLVD) to one of the values from ICC to ICCH. In addition, when both the low-voltage detection reset circuit and a CR oscillator are selected, the power supply current is the sum of adding up the
current consumption of the low-voltage detection reset circuit (IPLVD), the current consumption of the CR
oscillator (ICRH or ICRL) and one of the values from ICC to ICCH. In on-chip debug mode, the main CR oscillator (ICRH) and the low-voltage detection reset circuit are always in operation, and current consumption
therefore increases accordingly.
• See “4. AC Characteristics (1) Clock Timing” for FCH, FCL, FCRH, FMCRPLL and FMPLL.
• See “4. AC Characteristics (2) Source Clock/Machine Clock” for FMP and FMPL.
• The power supply current in subclock mode is determined by the external clock. In subclock mode, current
consumption in using the crystal oscillator is higher than that in using the external clock. When the crystal
oscillator is used, the power supply current is the sum of adding ISOSC (current consumption of the suboscillator) to the power supply current in using the external clock. For details of controlling the subclock, refer
to “CHAPTER 3 CLOCK CONTROLLER” and “CHAPTER 30 SYSTEM CONFIGURATION REGISTER”
in “New 8FX MB95710L/770L Series Hardware Manual”.

Normal mode ⇔ Low power
consumption mode
Note: When being used for interrupt, the low-voltage detection circuit can be switched between normal mode
and low power consumption mode. Compared with normal mode, in low power consumption mode, while
the detection voltage and release voltage are less accurate, and the detection delay time and the release
delay time become longer, there is less power consumption. For the difference in power consumption
between normal mode and low power consumption mode, see “3. DC Characteristics”. For the method
of switching between normal mode and low power consumption mode, refer to “CHAPTER 16 LOWVOLTAGE DETECTION CIRCUIT” in “New 8FX MB95710L/770L Series Hardware Manual”.

(2) Notes on Using A/D Converter
• External impedance of analog input and its sampling time
The A/D converter of the MB95710L/770L Series has a sample and hold circuit. If the external impedance
is too high to keep sufficient sampling time, the analog voltage charged to the capacitor of the internal sample and hold circuit is insufficient, adversely affecting A/D conversion precision. Therefore, to satisfy the A/D
conversion precision standard, considering the relationship between the external impedance and minimum
sampling time, either adjust the register value and operating frequency or decrease the external impedance
so that the sampling time is longer than the minimum value. In addition, if sufficient sampling time cannot
be secured, connect a capacitor of about 0.1 µF to the analog input pin.

Note: The values are reference values.
• Relationship between external impedance and minimum sampling time
The necessary sampling time varies according to external impedance. Ensure that the following conditions
are fulfilled when setting the sampling time.
Ts ≥ ( Rin + Rext ) × Cin × 9
Ts : Sampling time
Rin : Input resistance of A/D converter
Cin : Input capacitance of A/D converter
Rext : Output impedance of external circuit
• A/D conversion error
As |VCC − VSS| decreases, the A/D conversion error increases proportionately.

(3) Definitions of A/D Converter Terms
• Resolution
It indicates the level of analog variation that can be distinguished by the A/D converter.
When the number of bits is 12, analog voltage can be divided into 212 = 4096.
• Linearity error (unit: LSB)
It indicates how much an actual conversion value deviates from the straight line connecting the zero transition point (“000000000000” ← → “000000000001”) of a device to the full-scale transition point
(“111111111111” ← → “111111111110”) of the same device.
• Differential linear error (unit: LSB)
It indicates how much the input voltage required to change the output code by 1 LSB deviates from an ideal
value.
• Total error (unit: LSB)
It indicates the difference between an actual value and a theoretical value. The error can be caused by a
zero transition error, a full-scale transition errors, a linearity error, a quantum error, or noise.
