SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
MEMORY MODIFICATION FUNCTION
The M37753M8C-XXXFP and M37753M8C-XXXHP’s internal
memory size and address area can be modified by set of bit 2
(memory allocation select bit) of the particular function select regis-
ter 0. Figure 87 shows the memory allocation when modifying the in-
ternal 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.
