In parallel I/O mode, the user ROM area and the boot ROM area can be rewritten by a parallel programmer
supporting the M32C/85 Group (M32C/85, M32C/85T). Contact your parallel programmer manufacturer for
more information on the parallel programmer. Refer to the user's manual included with your parallel pro-
grammer for instructions.

An erase block operation in the boot ROM area is applied to only one 4-Kbyte block. The rewrite control
program in standard serial I/O mode is written in the boot ROM area before shipment. Do not rewrite the
boot ROM area if using the serial programmer.
In parallel I/O mode, the boot ROM area is located in addresses FFF000
address range only if rewriting the boot ROM area. (Do not access addresses other than addresses
FFF000
The ROM code protect function prevents the flash memory from being read and rewritten in parallel I/O
mode. (Refer to 25.2 Functions to Prevent Flash Memory from Rewriting.)
