Fig. 77 Block diagram of built-in flash memory
q Boot Mode
The control program for CPU rewrite mode must be written into
the User ROM or Boot ROM area in parallel I/O mode beforehand.
(If the control program is written into the Boot ROM area, the stan-
dard serial I/O mode becomes unusable.)
See Figure 77 for details about the Boot ROM area.
Normal microcomputer mode is entered when the microcomputer
is reset with pulling CNVSS pin low. In this case, the CPU starts
operating using the control program in the User ROM area.
When the microcomputer is reset and the CNVSS pin high after
pulling the P45/TxD1 pin and CNVss pin high, the CPU starts op-
erating (start address of program is stored into addresses FFFC16
and FFFD16) using the control program in the Boot ROM area.
This mode is called the “Boot mode”. Also, User ROM area can be
rewritten using the control program in the Boot ROM area.
q Block Address
Block addresses refer to the maximum address of each block.
These addresses are used in the block erase command.
q CPU Rewrite Mode
In CPU rewrite mode, the internal flash memory can be operated
on (read, program, or erase) under control of the Central Process-
ing Unit (CPU).
In CPU rewrite mode, only the User ROM area shown in Figure 77
can be rewritten; the Boot ROM area cannot be rewritten. Make
sure the program and block erase commands are issued for only
the User ROM area and each block area.
The control program for CPU rewrite mode can be stored in either
User ROM or Boot ROM area. In the CPU rewrite mode, because
the flash memory cannot be read from the CPU, the rewrite con-
trol program must be transferred to internal RAM area before it
can be executed.

lel I/O mode. (Access to except boot ROM
area is disablrd.)

in the block.
