9.4.2 Port Operating Modes
The I/O Ports have several modes of operation. Some modes can be defined in
PSDsoft, some by the microcontroller writing to the Control Registers in CSIOP space, and
some by both. The modes that can only be defined using PSDsoft must be
programmed into the device and cannot be changed unless the device is reprogrammed.
The modes that can be changed by the microcontroller can be done so dynamically
at run-time. The PLD I/O, Data Port, and Address Input, are the only modes that must
be defined before programming the device. All other modes can be changed by the
microcontroller at run-time.
Table 20 summarizes which modes are available on each port. Table 23 shows how and
where the different modes are configured. Each of the port operating modes are described
in the following subsections.
