PSD7XX Interface To a Multiplexed Bus
Figure 11 shows an example of a system using a microcontroller with a multiplexed
bus and a PSD7XX. The ADIO port on the PSD7XX is connected directly to the
microcontroller address/data bus. The bus may be multiplexed only on one byte (eight-bit
data) or on both bytes (sixteen-bit data). The ALE latches the address lines internally;
latched addresses can be brought out to Port A or B. The PSD7XX drives the ADIO data
bus only when one of its internal resources is accessed and the RD input is active.
