19.7 Standard Serial Input/Output 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/1N 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.

There are actually two standard serial I/O modes: mode 1, which is clock synchronized, and mode 2,

which is asynchronized.

Table 19.7 lists pin functions (flash memory standard serial I/O mode). Figure 19.13 shows pin connec-

tions for standard serial I/O mode.

19.7.1 ID code check function

This function determines whether the ID codes sent from the serial programmer and those written in

the flash memory match (refer to the description of 19.3 Functions to Inhibit Rewriting Flash

Memory Version).
