(3) Read/write signals
With a 16-bit data bus (BYTE pin =“L”), bit 2 of the processor mode register 0 (address 000416) select the
_____ ________

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 000416) to “0”.) Tables 7 and 8 show the operation of these signals.
_____
______
________
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 000416) has been set (Note).

________
Table 1.8. Operation of RD, WR, and BHE signals
Note: Before attempting to change the contents of the processor mode register 0, set bit 1 of the protect
register (address 000A16) to “1”.
