The ADIO port on the PSD is connected directly to the MCU address/data bus. Address Strobe (ALE/AS, PD0) latches the address signals internally. Latched addresses can be brought out to Port A or B. The PSD drives the ADIO data bus only when one of its internal resources is accessed and Read Strobe (RD, CNTL1) is active. Should the system address bus exceed sixteen bits, Ports A, B, C, or D may be used as additional address inputs. Figure 19.
