In memory expansion mode or microprocessor mode, some pins function as bus control pins to control the
address bus and data bus. A
HLDA/ALE, HOLD, ALE, RDY are used as bus control pins.
The BYTE pin, the DS register, the PM05 and PM04 bits in the PM0 register, and the PM11 and PM10 bits
in the PM1 register determine bus settings.
Table 7.1 lists how to change bus settings. Figure 7.1 shows the DS register.
