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 standard serial I/O mode becomes unusable.)
See Figure.64 for details about the Boot ROM area.
Normal microcompu ter mo de is e n t e red 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
operating (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.
Block Address
Block addresses refer to the maximum address of each block.
These addresses are used in the block erase command.
CPU Rewrite Mode
In CPU rewrite mode, the internal flash memory can be operated
on (read, program, or erase) under control of the Central
Processing Unit (CPU).
In CPU rewrite mode, only the User ROM area shown in
Figure.64 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 control program must be transferred to internal RAM
area before it can be executed.

: To specify a block, use the maximum
address in the block.
