BASIC FUNCTION BLOCKS
The M37754FFCGP and the M37754FFCHP have the same func-
tions as the M37754M8C-XXXGP and the M37754M8C-XXXHP ex-
cept for the following.
Therefore, refer to the section on the M37754M8C-XXXGP and the
M37754M8C-XXXHP.
(1) Flash memory is included instead of ROM.
(2) The memory size is different.
(3) The memory area modification function is different.
(4) Part of the peripheral devices control registers is different.
(Flash memory control register, flash command register, and bits
3, 4 of particular function select register 0 are added.)

: The flash memory area (8 Kbytes) where it is impossible to erase/modify in the CPU reprogramming mode.
(It is possible to erase/modify in the parallel I/O mode or the serial I/O mode.)
Note: The internal memory area can be changed. (Refer to the section on the memory area modification function.)
