33.5.1
In standard serial I/O mode, a serial programmer which supports the MCU can be used to rewrite the user ROM
area while the MCU is mounted on-board.
There are three types of standard serial I/O modes:
•
•
•
Standard serial I/O mode 2 and standard serial I/O mode 3 can be used for the MCU.
Refer to Appendix 2. Connection Examples with M16C Flash Starter for examples of connecting to a serial
programmer. Contact the serial programmer manufacturer for more information. Refer to the user’s manual
included with your serial programmer for instructions.
Table 33.7 lists the Pin Functions (Flash Memory Standard Serial I/O Mode 2) and Figure 33.16 shows Pin
Handling in Standard Serial I/O Mode 2. Table 33.8 lists the Pin Functions (Flash Memory Standard Serial I/O
Mode 3) and Figure 33.17 shows Pin Handling in Standard Serial I/O Mode 3.
After handling the pins shown in Table 33.8 and rewriting the flash memory using the programmer, apply a high-
level signal to the MODE pin and reset the hardware to run a program in the flash memory in single-chip mode.
Standard serial I/O mode 1 .................Clock synchronous serial I/O used to connect to a serial programmer
Standard serial I/O mode 2 .................Clock asynchronous serial I/O used to connect to a serial programmer
Standard serial I/O mode 3 .................Special clock asynchronous serial I/O used to connect to a serial
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 12. ID Code Areas for details of the ID code check.
