18.9 Standard Serial I/O Mode
In standard serial I/O mode, the serial programmer supporting the M16C/28 group can be used to rewrite
the flash memory user ROM area, while the microcomputer is mounted on a board. For more information
about the serial programmer, contact your serial programmer manufacturer. Refer to the user's manual
included with your serial programmer for instruction.
Table 18.8 lists pin description (flash memory standard serial input/output mode). Figures 18.16 and
18.17 show pin connections for standard serial input/output mode.
18.9.1 ID Code Check Function
The ID code check function determines whether or not the ID codes sent from the serial programmer
matches those written in the flash memory. (Refer to 18.3 Functions To Prevent Flash Memory from
Rewriting.)
