SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
MEMORY MODIFICATION FUNCTION
The M37754M8C-XXXGP’s internal memory size and address area
can be modified by set of bit 2 (memory allocation select bit) of the
particular function select register 0. Figure 90 shows the memory al-
location when modifying the internal memory area.
When ordering a mask ROM, Mitsubishi Electric corp. produces the
mask ROM using the data within 60 Kbytes (between addresses
00100016 to 00FFFF16). It is regardless of the selected ROM size
(refer to MASK ROM ORDER CONFIRMATION FORM). Therefore,
on the EPROM tendered for ordering a mask ROM, program data
“FF16” to addresses which correspond to the area out of the selected
ROM area.
Additionally, address 00FFFF16 of the microcomputer corresponds
to the lowest address of the tendered EPROM.

External memory area
Memory allocation select bit = “0”
ROM size : 60 Kbytes
RAM size : 2048 bytes
Memory allocation select bit = “1”
ROM size : 56 Kbytes
RAM size : 2048 bytes
External memory area
Note : The internal ROM area becomes external memory area
in microprocessor mode.
