30.6.1
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 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 30.1 can be rewritten.
The ROM code protect function prevents the flash memory from being read and rewritten. (Refer to the 30.3.2
ROM Code Protect Function.)
