18.6.1
Parallel I/O mode is used to input and output software commands, addresses, and data necessary to control (read,
program, and erase) the on-chip flash memory. Use a parallel programmer which supports this MCU. Contact the
manufacturer of the parallel programmer for more information, and refer to the user’s manual of the parallel
programmer for details on how to use it.
ROM areas shown in Figures 18.1 and 18.2 can be rewritten in parallel I/O mode.
The ROM code protect function disables the reading and rewriting of the flash memory. (Refer to the 18.3
Functions to Prevent Rewriting of Flash Memory.)
