4. SWITCHING FUNCTION BETWEEN Mk I AND Mk II MODE
Setting a stack bank selection (SBS) register for the µPD75P3018 enables the program memory to be switched between
Mk I mode and Mk II mode. This function is applicable when using the µPD75P3018 to evaluate the µPD753012, 753016,
or 753017.
When the SBS bit 3 is set to 1 : sets Mk I mode (supports Mk I mode for µPD753012, 753016, and 753017)

Caution The Mk II mode supports a program area exceeding 16 Kbytes for the 75X and 75XL series. Therefore,
this mode is effective for enhancing software compatibility with products that have a program area of
more than 16 Kbytes.
With regard to the number of stack bytes during execution of subroutine call instructions, the usable
area increases by 1 byte per stack compared to the Mk I mode when the Mk II mode is selected.
However, when the CALL !addr and CALLF !faddr instructions are used, the machine cycle becomes
longer by 1 machine cycle. Therefore, if more emphasis is placed on RAM use efficiency and
processing performance than on software compatibility, the Mk I mode should be used.

4.2 Setting of Stack Bank Selection Register (SBS)
Use the stack bank selection register to switch between Mk I mode and Mk II mode. Figure 4-1 shows the format for doing
this.
The stack bank selection register is set using a 4-bit memory manipulation instruction. When using the Mk I mode, be
sure to initialize the stack bank selection register to 10XXBNote at the beginning of the program. When using the Mk II mode,
be sure to initialize it to 00XXBNote.
Note Set the desired value for XX.

Cautions 1. SBS3 is set to “1” after RESET input, and consequently the CPU operates in Mk I mode. When using
instructions for Mk II mode, set SBS3 to “0” and set Mk II mode before using the instructions.
2. When using Mk II mode, execute a subroutine call instruction and an interrupt instruction after
RESET input and after setting the stack bank selection register.

5. DIFFERENCES BETWEEN µPD75P3018 AND µPD753012, 753016, AND 753017
The µPD75P3018 replaces the internal mask ROM in the µPD753012, 753016, and 753017 with a one-time PROM and
features expanded ROM capacity. The µPD75P3018’s Mk I mode supports the Mk I mode in the µPD753012, 753016,
and 753017 and the µPD75P3018’s Mk II mode supports the Mk II mode in the µPD753012, 753016, and 753017.
Table 5-1 lists differences among the µPD75P3018 and the µPD753012, 753016, and 753017. Be sure to check the
differences among these products before using them with PROMs for debugging or prototype testing of application
systems or, later, when using them with a mask ROM for full-scale production.
For the CPU functions and internal hardwares, refer to µPD753017 User's Manual (U11282E).

Noise resistance and noise radiation may differ due to the different circuit sizes and mask
layouts.
Note For 217/fX, during 6.0 MHz operation is 21.8 ms, and during 4.19 operation is 31.3 ms.
For 215/fX, during 6.0 MHz operation is 5.46 ms, and during 4.19 operation is 7.81 ms.
Caution Noise resistance and noise radiation are different in PROM and mask ROMs. In transferring to mask
ROM versions from the PROM version in a processe between prototype development and full
production, be sure to fully evaluate the mask ROM version’s CS (not ES).

7. INSTRUCTION SET
(1) Representation and coding formats for operands
In the instruction’s operand area, use the following coding format to describe operands corresponding to the instruction’s
operand representations (for further description, see theRA75X Assembler Package User’s Manual –Language (EEU1363)). When there are several codes, select and use just one. Codes that consist of upper-case letters and + or – symbols
are key words that should be entered as they are.
For immediate data, enter an appropriate numerical value or label.
Enter register flag symbols as label descriptors instead of mem, fmem, pmem, bit, etc. (For details, refer to the User's
Manual). The number of labels that can be entered for fmem and pmem are restricted.

8.2 Program Memory Write Procedure
Program memory can be written at high speed using the following procedure.
(1) Pull unused pins to Vss through resistors. Set the X1 pin low.
(2) Supply 5 V to the VDD and VPP pins.
(3) Wait 10 µs.
(4) Select the zero-clear program memory address mode.
(5) Supply 6 V to the VDD and 12.5 V to the VPP pins.
(6) Select the program inhibit mode.
(7) Write data in the 1 ms write mode.
(8) Select the program inhibit mode.
(9) Select the verify mode. If the data is correct, go to step (10) and if not, repeat steps (7) to (9).
(10) (X : number of write operations from steps (7) to (9)) x 1 ms additional write.
(11) Select the program inhibit mode.
(12) Apply four pulses to the X1 pin to increment the program memory address by one.
(13) Repeat steps (7) to (12) until the end address is reached.
(14) Select the zero-clear program memory address mode.
(15) Return the VDD and VPP pins back to 5 V.
(16) Turn off the power.

8.4 One-time PROM Screening
Due to its structure, the one-time PROM cannot be fully tested before shipment by NEC. Therefore, NEC recommends
that after the required data is written and the PROM is stored under the temperature and time conditions shown below,
the PROM should be verified via a screening.

Notes 1. The oscillation frequency and X1 input frequency shown above indicate characteristics of the oscillation circuit
only. For the instruction execution time, refer to AC Characteristics.
2. When the supply voltage is 1.8 V ≤ VDD < 2.7 V and the oscillation frequency is 4.19 MHz < fX ≤ 6.0 MHz, do
not select processor clock control register (PCC) = 0011 as the instruction execution time. If PCC = 0011, one
machine cycle is less than 0.95 µs, falling short of the rated value of 0.95 µs.
3. The oscillation stabilization time is the time required for oscillation to be stabilized after VDD has been applied
or STOP mode has been released.
Caution When using the main system clock oscillation circuit, wire the portion enclosed in the broken line in
the above figure as follows to prevent adverse influences due to wiring capacitance:
• Keep the wiring length as short as possible.
• Do not cross the wiring with other signal lines.
• Do not route the wiring in the vicinity of a line through which a high alternating current flows.
• Always keep the ground point of the capacitor of the oscillation circuit at the same potential as VDD.
• Do not ground to a power supply pattern through which a high current flows.
• Do not extract signals from the oscillation circuit.

2. The oscillation stabilization time is the time required for oscillation to be stabilized after VDD has been applied.
Caution When using the subsystem clock oscillation circuit, wire the portion enclosed in the broken line in the

• Do not ground to a power supply pattern through which a high current flows.
• Do not extract signals from the oscillation circuit.
The subsystem clock oscillation circuit has a low amplification factor to reduce current dissipation and
is more susceptible to noise than the main system clock oscillation circuit. Therefore, exercise utmost
care in wiring the subsystem clock oscillation circuit.

NOTES FOR CMOS DEVICES
1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note: Strong electric field, when exposed to a MOS device, can cause destruction of
the gate oxide and ultimately degrade the device operation. Steps must be taken
to stop generation of static electricity as much as possible, and quickly dissipate
it once, when it has occurred. Environmental control must be adequate. When
it is dry, humidifier should be used. It is recommended to avoid using insulators
that easily build static electricity. Semiconductor devices must be stored and
transported in an anti-static container, static shielding bag or conductive
material. All test and measurement tools including work bench and floor should
be grounded. The operator should be grounded using wrist strap. Semiconductor
devices must not be touched with bare hands. Similar precautions need to be
taken for PW boards with semiconductor devices on it.
2 HANDLING OF UNUSED INPUT PINS FOR CMOS
Note: No connection for CMOS device inputs can be cause of malfunction. If no
connection is provided to the input pins, it is possible that an internal input level
may be generated due to noise, etc., hence causing malfunction. CMOS devices
behave differently than Bipolar or NMOS devices. Input levels of CMOS devices
must be fixed high or low by using a pull-up or pull-down circuitry. Each unused
pin should be connected to VDD or GND with a resistor, if it is considered to have
a possibility of being an output pin. All handling related to the unused pins must
be judged device by device and related specifications governing the devices.
3 STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note: Power-on does not necessarily define initial status of MOS device. Production
process of MOS does not define the initial operation status of the device.
Immediately after the power source is turned ON, the devices with reset function
have not yet been initialized. Hence, power-on does not guarantee out-pin
levels, I/O settings or contents of registers. Device is not initialized until the
reset signal is received. Reset operation must be executed immediately after
power-on for devices having reset function.

While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a
customer designated "quality assurance program" for a specific application. The recommended applications of
a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device
before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact an NEC sales representative in advance.
Anti-radioactive design is not implemented in this product.
