In standard serial I/O mode, the user ROM area can be rewritten while the MCU is mounted on-board by using a
serial programmer which is applicable for the MCU.
There are three types of Standard serial I/O modes:
This MCU uses Standard serial I/O mode 2 and Standard serial I/O mode 3.
Refer to Appendix 2. Connection Examples 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 19.7 lists the Pin Functions (Flash Memory Standard Serial I/O Mode 2), Table 19.8 lists the Pin Functions
(Flash Memory Standard Serial I/O Mode 3), Figure 19.17 shows Pin Connections for Standard Serial I/O Mode 3.
After processing the pins shown in Table 19.8 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 19.3 Functions to Prevent Rewriting of Flash Memory).
Standard serial I/O mode 1 . . . . Clock synchronous serial I/O used to connect with a serial programmer
Standard serial I/O mode 2 . . . . Clock asynchronous serial I/O used to connect with a serial programmer
Standard serial I/O mode 3 . . . . Special clock asynchronous serial I/O used to connect with a serial programmer
