In memory expansion mode or microprocessor mode, some pins function as bus control pins to input and
output data from external devices. A
WRH/BHE/CASH, RD/DW, BCLK/ALE, HLDA/ALE, HOLD, ALE/RAS, and RDY are used as bus control
pins.

Bus control pins in M32C/83T cannot be used.
The BYTE pin, the DS register, the PM05 to PM04 bits in the PM0 register and the PM11 to PM10 bits in
the PM1 register determine bus settings.
Table 7.1 lists how to change a bus setting. Figure 7.1 shows the DS register.
