ZPSD6XX(V) Interface To a Multiplexed Bus
Figure 11 shows an example of a system using a microcontroller with a multiplexed
bus and a ZPSD6XX(V). The ADIO port on the ZPSD6XX(V) 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 ZPSD6XX(V) drives the ADIO
data bus only when one of its internal resources is accessed and the RD input is active.
