■ HANDLING DEVICES
• Preventing Latchup
Latch-up may occur in a CMOS IC if a voltage greater than VCC or less than VSS is applied to an input or output
pin or if an above-rating voltage is applied between VCC and VSS. A latchup,if it occurs, significantly increases
the power supply current and may cause thermal destruction of an element. When you use a CMOS IC, be very
careful not to exceed the maximum rating.
• Treatment of Unused Input Pins
Do not leave an unused input pin open, since it may cause a malfunction. Handle by, for example, using a pullup or pull-down resistor.
• About power supply pins
In products with multiple VCC or VSS pins, the pins of the same potential are internally connected in the device
to avoid abnormal operations including latch-up. However, you must connect the pins to an external power supply
and a ground line to lower the electro-magnetic emission level, to prevent abnormal operation of strobe signals
caused by the rise in the ground level, and to conform to the total output current rating.
Moreover, connect the current supply source with the VCC and VSS pins of this device at the low impedance.
It is also advisable to connect a ceramic bypass capacitor of approximately 0.1 µF between VCC and VSS near
this device.
• About Crystal oscillator circuit
Noise near the X0, X1, X0A and X1A pins may cause the device to malfunction. Design the circuit board so that
X0, X1, X0A, X1A, the crystal oscillator (or ceramic oscillator), and the bypass capacitor to ground are located
as close to the device as possible.
It is strongly recommended to design the PC board artwork with the X0, X1, X0A and X1A pins surrounded by
ground plane because stable operation can be expected with such a layout.
• Notes on Using External Clock
When external clock is selected, supply it to X0 pin generally, and simultaneously the opposite phase clock to
X0 must be supplied to X1 pin. However, in this case the stop mode(oscillator stop mode) must not be used.
(This is because the X1 pin stops at High level output in STOP mode.)
Using an external clock (normal)
X0
X1
Note: STOP mode (oscillation stop mode) cannot be used.
• Clock control block
Take the oscillation stabilization wait time during Low level input to the INIT pin.
17
MB91350A Series
• Notes on not using the sub clock
When no oscillator is connected to the X0A and X1A pins, pull down the X0A pin and open the X1A pin.
X0
OPEN
X1
MB91350A
• Treatment of NC and OPEN pins
Pins marked as NC and OPEN must be left open-circuit.
• Mode pins (MD0 to MD2)
These pins should be connected directly to VCC or VSS.
To prevent the device erroneously switching to test mode due to noise, design the printed circuit board such that
the distance between the mode pins and VCC or VSS is as short as possible and the connection impedance is low.
• Operation at start-up
The INIT pin must be at Low level when the power supply is turned on.
Immediately after the power supply is turned on, hold the Low level input to the INIT pin for the settling time
required for the oscillator circuit to take the oscillation stabilization wait time for the oscillator circuit. (For INIT
via the INIT pin, the oscillation stabilization wait time setting is initialized to the minimum value.)
• About oscillation input at power on
When turning the power on, maintain clock input until the device is released from the oscillation stabilization
wait state.
• Caution on Operations during PLL Clock Mode
Even if the oscillator comes off or the clock input stops with the PLL clock selected for this microcontroller, the
microcontroller may continue to operate at the free-running frequency of the PLL’s internal self-oscillating oscillator circuit. Performance of this operation, however, cannot be guaranteed.
• External bus setting
This model guarantees an external bus frequency of 25 MHz.
Setting the base clock frequency to 50 MHz with DIVR1 (external bus base clock division setting register)
initialized sets the external bus frequency also to 50 MHz. Before changing the base clock frequency, set the
external bus frequency not exceeding 25 MHz.
• MCLK and SYSCLK
MCLK and SYSCLK has a difference that MCLK stops in SLEEP/STOP mode but SYSCLK stops only in STOP
mode. Use either depending on each application.
Upon initialization, MCLK becomes invalid (PORT) and SYSCLK becomes valid. To use MCLK, set the port
function register (PFR) to select the use of that clock.
• Pull-up control
Connecting a pull-up resistor to the pin serving as an external bus pin cannot a guarantee the “■ ELECTRICAL
CHARACTERISTICS 4. AC Characteristics (4) Normal Bus Access Read/Write Operation, (5) Multiplex Bus
Access Read/Write operation and (7) Hold Timing”.
Even the port for which a pull-up resistor has been set is invalid in stop mode with HIZ = 1 or in hardware standby
mode.
18
MB91350A Series
• Sub clock select
Immediately after switching from main clock mode to subclock mode for the clock source, insert at least one
NOP instruction.
(ldi
#0x0b, r0)
(ldi
#_CLKR, r12)
stb
r0, @r12
// sub-clock mode
nop
// Must insert NOP instruction
• Bit Search Module
The BSD0, BSD1, and BDSC registers are accessed only in words.
• D-bus memory
Do not allocate the code area in memory on the D-bus because no instruction fetch takes place to the D-bus.
Executing an instruction fetch to the D-bus area causes wrong data to be interpreted as code, possibly letting
the device to run out of control.
• Low Power Consumption Mode
To enter the sleep or stop mode, be sure to read the standby control register (STCR) immediately after writing to it.
Precisely, use the following sequence.
Set the I flag, ILM, and ICR to, after returning from standby mode, branch to the interrupt handler having caused
the device to return.
(ldi
#value_of_standby, r0)
(ldi
#_STCR, r12)
stb
r0, @r12
// set STOP/SLEEP bit
ldub
@r12, r0
// Must read STCR
// after reading, go into standby
ldub
@r12, r0
mode
nop
// Must insert NOP *5
nop
nop
nop
nop
• Switch shared port function
To switch between the use as a port and the use as a dedicated pin, use the port function register (PFR). Note,
however, that bus pins are switched depending on external bus settings.
• Pre-fetch
When accessing a prefetch-enabled little endian area, be sure to use word access (in 32-bit, word length) only.
Byte or halfword access results in wrong data read.
• I/O port access
Ports are accessed only in bytes.
• Built-in RAM
Immediately after a reset is canceled, the internal RAM allocation restricting function is still working, allowing
only 4 KB to be used for data and for program execution irrespective of the on-chip RAM capacity.
19
MB91350A Series
• Flash memory
In programming mode, Flash memory cannot be used as an interrupt vector table. A reset is possible.
• Notes on the PS register
As the PS register is processed by some instructions in advance, exception handling below may cause the
interrupt handling routine to break when the debugger is used or the display contents of flags in the PS register
to be updated.
As the microcontroller is designed to carry out reprocessing correctly upon returning from such an EIT event, it
performs operations before and after the EIT as specified in either case.
1. The following operations are performed when the instruction followed by a DIVOU/DIVOS instruction results in:
(a) acceptance of a user interrupt or NMI, (b) single-stepping, or (c) a break at a data event or emulator menu.
• The D0 and D1 flags are updated in advance.
• An EIT handling routine (user interrupt, NMI, or emulator) is executed.
• Upon returning from the EIT, the DIVOU/DIVOS instruction is executed and the D0 and D1 flags are
updated to the same values as in (1).
2. The following operations are performed when the ORCCR/STILM/MOVRi and PS instructions are executed.
• The PS register is updated in advance.
• An EIT handling routine (user interrupt, NMI, or emulator) is executed.
• Upon returning from the EIT, the above instructions are executed and the PS register is updated to the
same value as in (1).
20
MB91350A Series
[Note on debugger]
• Step execution of RETI command
If an interrupt occurs frequently during single-stepping, the corresponding interrupt handling routine is executed
repeatedly. This will prevent the main routine and low-interrupt-level programs from being executed. (Whenever
RETI is single-stepped when interrupts by the timebase timer have been enabled, for example, the timebase
timer routine causes a break at the beginning.)
Disable the corresponding interrupt when the corresponding interrupt handling routine no longer needs debugging.
• Break function
If the address at which to cause a hardware break (including a event break) is set to the address currently
contained in the system stack pointer or in the area containing the stack pointer, the user program causes a
break after execution of one instruction.
To prevent this, do not set (word) access to the area containing the address in the system stack pointer as the
target of a hardware break (including an event break).
• Internal ROM area
Do not set an area of internal ROM as a DMAC transfer destination.
• Simultaneous occurrences of a software break (INTE instruction) and a user interrupt/NMI
When an INTE instruction and a user interrupt/NMI are accepted simultaneously, the emulator debugger reacts
as follows.
The emulator debugger stops while indicating a location in the user program, which is not a user-specified
breakpoint. (It stops with the beginning of the user interrupt/NMI handling routine indicated.)
The user program cannot be re-executed correctly.
To prevent this problem, follow the instructions below.
When a software break and a user interrupt/NMI occur simultaneously, the emulator debugger may react as
follows.
• The debugger stops pointing to a location other than the programmed breakpoints.
• The halted program is not re-executed correctly.
If this symptom occurs, use a hardware break in place of a hardware break. When using a monitor debugger,
do not set a break at the relevant location.
• A stack pointer placed in an area set for a DSU operand break can cause a malfunction. Do not apply a data
event break to access to the area containing the address of a system stack pointer.

■ MODE SETTINGS
The FR family uses mode pins (MD2 to MD0) and a mode register (MODR) to set the operation mode.
1. Mode Pins
The MD2, MD1, and MD0 pins specify how the mode vector fetch is performed.

Remarks
The bus width is specified by the mode register.
Values other than those listed in the table are prohibited.
2. Mode Register (MODR)
The data written to the mode register at 000F FFF8H using mode vector fetch is called mode data.
After an operation mode has been set in the mode register (MODR), the device operates in the operation mode.
The mode register is set by any reset source. User programs cannot write data to the mode register.
Note : Conventionally the FR family has nothing at addresses (0000 07FFH) in the mode register.

■ MEMORY SPACE
1. Memory space
The FR family has 4 GB of logical address space (232 addresses) available to the CPU by linear access.
• Direct Addressing Areas
The following address space areas are used as I/O areas.
These areas are called direct addressing areas, in which the address of an operand can be specified directly
during an instruction.
The size of directly addressable areas depends on the length of the data being accessed as shown below.
→ byte data access
: 000H to 0FFH
→ half word data access : 000H to 1FFH
→ word data access
: 000H to 3FFH

*1 : The parameter is based on VSS = DAVS = AVSS = 0 V.
*2 : VCC must not be lower than VSS - 0.3 V.
*3 : Be careful not to exceed "VCC + 0.3 V”, for example, when the power is turned on.
*4 : The maximum output current is the peak value for a single pin.
*5 : The average output current is the average current for a single pin over a period of 100 ms.
*6 : The total average output current is the average current for all pins over a period of 100 ms.

*7 : • Relevant pins: Port2, 3, 4, 5, 6, 8, 9, A, B, C, G, H, I, J, K, M, N, O, P, and AN (A/D input)
• Use within recommended operating conditions.
• Use at DC voltage (current).
• The + B signal should always be applied a limiting resistance placed between the + B signal and
the microcontroller.
• The value of the limiting resistance should be set so that when the + B signal is applied the input current to
the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods.
• Note that, when the microcontroller drive current is low as in low power consumption mode, the + B input
potential can increase the potential at the VCC pin via a protective diode, possibly affecting other devices.
• Note that, if the + B input exists when the microcontroller is off (not fixed at 0 V), power is supplied through
the pin, possibly causing the microcontroller to operate imperfectly.
• Note that, if the + B input exists when the power supply is turned on, power is supplied through the pin,
possibly resulting in a power-supply voltage at which a power-on reset does not work.
• Be careful not to let the + B input pin open.
• Note that the analog I/O pins (such as the LCD drive and comparator input pins) other than the A/D input pin
cannot input + B.
• Sample recommended circuits:
• Input/output equivalent circuits

*8: VI should not exceed the specified ratings. However, if the maximum current to/from an input is limited by some
means with external components, the ICLAMP rating supersedes the VI rating.
WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.

• About the external impedance of the analog input and its sampling time
• A/D converter with sample and hold circuit. If the external impedance is too high to keep sufficient sampling
time, the analog voltage charged to the internal sample and hold capacitor is insufficient, adversely affecting
A/D conversion precision.
