MCU BUS INTERFACE
The
no-glue logic
PSD 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
15
. The interface type
is specified using the PSDsoft Express Configura-
tion.
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-
tions.
2. ALE/AS input is optional for MCUs with a non-multiplexed bus
