FLASH MEMORY MODE
The 38D5 Group flash memory version has the flash memory
that can be rewritten with a single power source.
For this flash memory, three flash memory modes are available
in which to read, program, and erase: the parallel I/O and
standard serial I/O modes in which the flash memory can be
manipulated using a programmer and the CPU rewrite mode in
which the flash memory can be manipulated by the Central
Processing Unit (CPU). For details of each mode, refer to the
next and after pages. Contact the manufacturer of your
programmer for the programmer. Refer to the user's manual of
your programmer for details on how to use it.

1. The Boot ROM area has had a standard serial I/O mode control program stored in it when shipped from the factory.
This Boot ROM area can be erased and written in only parallel I/O mode.

This flash memory version has some blocks on the flash memory
as shown in Figure 70 and each block can be erased.
In addition to the ordinary User ROM area to store the MCU
operation control program, the flash memory has a Boot ROM
area that is used to store a program to control rewriting in CPU
rewrite and standard serial I/O modes. This Boot ROM area has
had a standard serial I/O mode control program stored in it when
shipped from the factory. However, the user can write a rewrite
control program in this area that suits the user’s application
system. This Boot ROM area can be rewritten in only parallel I/O
mode.
