In standard serial I/O mode, the serial programmer supporting the M32C/85 group (M32C/85, M32C/85T)
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 instructions.
Table 25.7 lists pin descriptions (flash memory standard serial I/O mode). Figures 25.14 to 25.16 show pin
connections in serial I/O mode.
