Table 13.Microcontroller Busses and Control Signals
The “no-glue logic” PSD7XX Microcontroller Bus Interface can be directly connected to the
most popular microcontrollers. Some of these microcontrollers with their bus types and
control signals are shown in Table 13. The interface type is specified using the PSDsoft
tools.
**
*Not used CNTL2 pin can be configured as GPLD input. Other not used 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.
***This configuration is for 68HC12 with non-mux bus.
Table 13 shows the names of the PSD7XX bus interface control pins and their functions.
The control pins have multiple functions and can be configured to interface to many
microcontrollers. Depending on the microcontroller, some of the control input pins are not
required and may be used as GPLD input or other I/O functions. Specific examples of
interfaces to different microcontrollers are provided in the following sections. For
microcontrollers that have more than 16 address lines, Port A, B, or C pins may be used as
additional address inputs
