FLASH MEMORY MODE
The M37516F8 (flash memory version) has an internal new
DINOR (DIvided bit line NOR) flash memory that can be rewritten
with a single power source when V

dard serial I/O modes.
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).

Summary
Table 13 lists the summary of the M37516F8 (flash memory ver-
sion).
The flash memory of the M37516F8 is divided into User ROM area
and Boot ROM area as shown in Figure 57.
In addition to the ordinary User ROM area to store the MCU op-
eration 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 sys-
tem. This Boot ROM area can be rewritten in only parallel I/O
mode.
