Fig. 8.2.3 Bank Control Register
8.2.10 Expansion ROM (only M37281MKH-
XXXSP/M37281EKSP)
The M37281MKH-XXXSP/M37281EKSP 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 (M37281ERSS), 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 M37281MKH-XXXSP, fix bit 7 of the bank control register to
“
1.
”
For M37281MAH-XXXSP and M37281MFH-XXXSP, fix the ad-
dress 00ED
16
to
“
00
16
.
