SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER FLASH MEMORY VERSION
MITSUBISHI MICROCOMPUTERS
Flash Memory Parallel I/O Mode
The flash memory parallel I/O mode is used to manipulate the inter-
nal flash memory with a parallel programmer. This parallel program-
mer uses the software commands listed in Table 25 to do the flash
memory manipulations, such as read/programming/erase opera-
tions.
In the flash memory parallel I/O mode, each block can be protected
from erasing/programming (in other words, block lock).

Note:
Programming is performed in a unit of 256 bytes, with the low-order
address assigned in the range of 00

(byte addresses).
User ROM Area and Boot ROM Area
The user ROM area and boot ROM area can be reprogrammed in
the flash memory parallel I/O mode.
The programming and block erase operations can be performed only
to these areas.
The boot ROM area, 16 Kbytes in size, is assigned to addresses
0000
16
–
3FFF
16
(byte addresses), so that programming and block
erase operations can be performed only to this area. (Access to any
address out of this area is prohibited).
The erasable block in the boot ROM area is only one block, consist-
ing of 16 Kbytes. The reprogramming control firmware to be used in
the flash memory serial I/O mode has been stored to this boot ROM
area on our shipment. Therefore, do not reprogram the boot ROM
area if the user uses the flash memory serial I/O mode.
Addresses FFB0
16
to FFBF
16
are the reserved area for the serial
programmer. Therefore, when the user uses the flash memory serial
I/O mode, do not program to this area.
Note that, when the boot ROM area is read out from the CPU in the
CPU reprogramming mode, described later, its addresses will be
shifted to C000
