MCU BUS INTERFACE
The “no-glue logic” PSD MCU Bus Interface block
can be directly connected to most popular MCUs
and their control signals.
Table 15. MCUs and their Control Signals
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-
