20.6.1
Parallel I/O mode is used to input and output the required software command, address and data parallel to controls
(read, program and erase) for internal flash memory. Use a parallel programmer which supports this MCU. Contact
the manufacturer of your parallel programmer about the parallel programmer and refer to the user’s manual of your
parallel programmer for details on how to use it.
User ROM area can be rewritten shown in Figure 20.1 and Figure 20.2 in parallel I/O mode.
The ROM code protect function disables to read and rewrite the flash memory. (Refer to 20.3 Functions to
Prevent Rewriting of Flash Memory.)
