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 the MCU. Contact the parallel programmer manufacturer for more
information. Refer to the user’s manual included with your parallel programmer for instructions.
In parallel I/O mode, the user ROM areas shown in Figure 32.1 can be rewritten.
The ROM code protect function prevents the flash memory from being read and rewritten. (Refer to the 32.3.2
