In standard serial I/O mode, the user ROM area can be rewritten while the microcomputer is mounted
on-board by using a serial programmer which is applicable for this microcomputer.
Standard serial I/O mode is used to connect with a serial writer using a special clock asynchronous serial
I/O.
There are three types of Standard serial I/O modes:
This microcomputer uses Standard serial I/O mode 2 and Standard serial I/O mode 3.
Refer to Appendix 2. Connecting Example between Serial Writer and On-Chip Debugging
Emulator. Contact the manufacturer of your serial programmer for serial programmer. Refer to the
user’s manual of your serial programmer for details on how to use it.
Table 18.7 lists the Pin Functions (Flash Memory Standard Serial I/O Mode 2), Table 18.8 lists the Pin
Functions (Flash Memory Standard Serial I/O Mode 3). Figure 18.15 show Pin Connections for Standard
Serial I/O Mode 3.
After processing the pins shown in Table 18.8 and rewriting a flash memory using a writer, apply “H” to
the MODE pin and reset a hardware if a program is operated on the flash memory in single-chip mode.

The ID code check function determines whether the ID codes sent from the serial programmer and
those written in the flash memory match (refer to 18.3 Functions To Prevent Flash Memory from
Rewriting ).
