In parallel I/O mode, the user ROM area and the boot ROM area (see Figure 25.1) can be rewritten by a
parallel programmer supporting the M32C/83 Group. 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.

Within the boot ROM area, 8K bytes equal one 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 a serial programmer.
In parallel I/O mode, the boot ROM area is allocated to addresses 0FFE000
only this address range when rewriting the boot ROM area. (Do not access addresses other than ad-
dresses 0FFE000
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.)
Standard serial I/O mode cannot be used if rewriting the boot ROM area in parallel I/O mode. (Refer to
25.4 Standard Serial I/O Mode.)
