With a 16-bit data bus (BYTE pin =“L”), bit 2 of the processor mode register 0 (address 0004
combinations of RD, BHE, and WR signals or RD, WRL, and WRH signals. With an 8-bit data bus (BYTE
pin = “H”), use the combination of RD, WR, and BHE signals. (Set bit 2 of the processor mode register 0
(address 0004
After a reset has been cancelled, the combination of RD, WR, and BHE signals is automatically selected.
When switching to the RD, WRL, and WRH combination, do not write to external memory until bit 2 of the
processor mode register 0 (address 0004
Note: Before attempting to change the contents of the processor mode register 0, set bit 1 of the protect

The ALE signal latches the address when accessing the multiplex bus space. Latch the address when the
ALE signal falls.
