PRELIMINARY
Notice: This is not a final specification.
Some paramentic limits are subject to change.
Rev. 1.0
Fig. 12.2.2 Bank Control Register
12.2.10 Expansion ROM (only M37280MK-
XXXSP/M37280EKSP)
The M37280MK-XXXSP/M37280EKSP can use 5-bank (total 20K
bytes) expansion ROM (4K bytes each bank) by setting the bank
register.
The expansion ROM is assigned to address 1B000
16
to 1FFFF
16
.
The contents of each bank in the expansion ROM are read by setting
the bank register and accessing addresses 1000
16
to 1FFF
16
. As the
expansion ROM is not programmable, use it as data-dedicated area.
When using the expansion ROM area, the internal ROM at addresses
1000
16
to 1FFF
16
(extra area) is not also programmable.
Notes 1:
When using the expansion ROM (BK7 = “1”), the ROM correction
function do not operate for addresses 1000
16
to 1FFF
16
.
2:
When using the emulator MCU (M37280ERSS), as addresses 1000
16
to FFFF
16
can be emulated by setting bit 7 of the bank control regis-
ter to “0,” the expansion ROM cannot be used. Addresses 2000
16
to
FFFF
16
can be emulated by setting it to “1.” The data in specified
area by the bank selection bits can be read by accessing addresses
1000
16
to 1FFF
16
.
3:
When using the emulator MCU, the expansion ROM and the extra
area cannot be emulated by setting bit 7 of the bank control register
to “1.” Therefore, write the data to this area before using.
4:
For the M37280MK-XXXSP, fix bit 7 of the bank control register to
“1.” For M37280MF-XXXSP, fix the address 00ED
16
to “00
16
.”
