9.3 Microcontroller Bus Interface
The
“
no-glue logic
”
PSD9XX Microcontroller Bus Interface can be directly connected to
most popular microcontrollers and their control signals. Key 8-bit microcontrollers with their
bus types and control signals are shown in Table 17. The interface type is specified using
the PSDsoft.

Unused CNTL2 pin can be configured as PLD input. Other unused pins (PC7, PD0, PA3-0) can be
**
configured for other I/O functions.

ALE/AS input is optional for microcontrollers with a non-multiplexed bus
9.3.1. PSD9XX Interface to a Multiplexed 8-Bit Bus
Figure 12 shows an example of a system using a microcontroller with an 8-bit multiplexed
bus and a PSD9XX. The ADIO port on the PSD9XX is connected directly to the
microcontroller address/data bus. ALE latches the address lines internally. Latched
addresses can be brought out to Port A or B. The PSD9XX drives the ADIO data bus only
when one of its internal resources is accessed and the RD input is active. Should the
system address bus exceed sixteen bits, Ports A, B, C, or D may be used as additional
address inputs.
9.3.2. PSD9XX Interface to a Non-Multiplexed 8-Bit Bus
Figure 13 shows an example of a system using a microcontroller with an 8-bit
non-multiplexed bus and a PSD9XX. The address bus is connected to the ADIO Port, and
the data bus is connected to Port A. Port A is in tri-state mode when the PSD9XX is not
accessed by the microcontroller. Should the system address bus exceed sixteen bits, Ports
B, C, or D may be used for additional address inputs.
