Standard Serial I/O Mode

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 suitable for the M16C/6N5 group. For more information about serial
programmers, contact the manufacturer of your serial programmer. For details on how to use, refer to the
user's manual included with your serial programmer.
Table 1.22.7 lists pin functions for standard serial I/O mode. Figures 1.22.13 shows pin connections for
standard serial I/O mode.
ID Code Check Function
This function determines whether the ID codes sent from the serial programmer and those written in the
