SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER FLASH MEMORY VERSION
MITSUBISHI MICROCOMPUTERS
FLASH MEMORY MODE
These microcomputers contain the DINOR (DIvided bit line NOR)-
type flash memory; and single-power-supply reprogramming is avail-
able to this. These microcomputers have the following three modes,
enabling reading/programming/erasure for the flash memory:
Flash memory parallel I/O mode and Flash memory serial I/O
mode, where the flash memory is handled by using an external pro-
grammer.
CPU reprogramming mode, where the flash memory is handled by
the central processing unit (CPU).
As shown in Figures 116 and 117, the flash memory is divided into
several blocks, and erasure per block is possible.
Each of these blocks is provided with a lock bit, which determines the
validity of erasure/program execution. Therefore, data protection per
block is possible.
This internal flash memory has the boot ROM area storing the repro-
gramming control software for reprogramming in the CPU repro-
gramming mode and flash memory serial I/O mode, as well as the
user ROM area storing a certain control software for the normal op-
eration in the microcomputer mode.
Although our reprogramming control firmware for the flash memory
serial I/O mode has been stored into this boot ROM area on ship-
ment, the user-original reprogramming control software which is
more appropriate for the user’s system is reprogrammable into this
area, instead. Note that the reprogramming for the boot ROM area is
enabled only in the flash memory parallel I/O mode.

Notes 1: In the flash memory mode, the read/programming/erase
operation cannot be performed for areas except for the
internal flash memory area.
2: The boot ROM area can be reprogrammed only in the
flash memory parallel I/O mode. When the boot ROM
area is read out by the CPU, these addresses are shifted
to addresses 00C00016–00FFFF16 (byte addresses).
3: The reserved area for the serial programmer is assigned
to addresses FFB016–FFBF16 (byte addresses). When
the flash memory serial I/O mode is used, do not
program to this area.
