There are additional registers in Spec.A as following table. These are used for additional function in Spec.A, software pull-up resister,Serial I/O2 and an increase of analog input pin number . When not using the additional functions in Spec.A, take the following (1) or (2) (1) Don’t write any data to the additional registers(or bit). (Keep the initial state after releasing Reset) (2) Write the initial state to the additional registers(or bit) after releasing Reset Additional Registers in Spec.A Address Spec.A Standard Version 001216 Port P0P1P2 pull-up control register – 001316 Port P3 pull-up control register – 001416 Port P4 pull-up control register – 001516 Serial I/O2 control register1 Reserved 001616 Serial I/O2 control register2 Reserved 001716 Serial I/O2 register Reserved 003716 Analog input selection register 003A16 bit4 Serial I/O2/INT3 interrupt source selection bit – Reserved • If in the program for Standard ver. any data have been not written to the addresses corresponding to the Spec.A’s additional registers, this program can be used for Spec.A as it is (not requiring to change program codes).

In Spec.A , Serial I/O2 interrupt request bit and enable bit are combined with those of INT3. Interrupt source can be selected by the Serial I/O2/INT3 interrupt source bit. When the Serial I/O2/INT3 interrupt source bit is “0”(initial state),interrupt source is INT3. This is the same as Standard version.

Spec.A’s emulator MCU is M38507ARLSS which is under development. When not using the additional functions, it is possible to develop program using M38517RSS 4. In Spec.A,the built-in pull-up resisters can be used for termination of unused pins. 5. There are differences in electric characteristics,operation margin,noise immunity and noise radiation between Spec.A and Standard version due to the difference in the manufacturing processes. When manufacturing an application system with Standard version switching to use of Spec.A, please perform sufficient evaluations for the commercial samples of Spec.A Mask ROM version. REJ99B0047-0100 -7- To our customers, Old Company Name in Catalogs and Other Documents On April 1st, 2010, NEC Electronics Corporation merged with Renesas Technology Corporation, and Renesas Electronics Corporation took over all the business of both companies. Therefore, although the old company name remains in this document, it is a valid Renesas Electronics document. We appreciate your understanding.
