3.0 Parallel Interface
3.2 MULTIPLEXED MODE
Multiplexed mode uses the control pins CS, RD, WR, the address latch enable signal ALE and the bidirectional address data
bus AD7-0 as shown in Figure 6. This mode is selected by tying MODE1 to GND and MODE0 to V
into the ADDR register when ALE is high. Data is output/input with the next active RD or WR signal. All registers are directly
accessible in this interface mode.
Figure 7 shows basic timing of the interface in Multiplexed mode.
