MCU BUS INTERFACE
The “no-glue logic” MCU Bus Interface block can
be directly connected to most popular MCUs and
their control signals. Key 8-bit MCUs, with their
bus types and control signals, are shown in Table
16. The interface type is specified using the PSD-
soft Express Configuration.

Note: 1. Unused CNTL2 pin can be configured as CPLD input. Other unused pins (PC7, PD0, PA3-0) can be configured for other I/O func-
tions.
2. ALE/AS input is optional for MCUs with a non-multiplexed bus
