9.4.2 Port Operating Modes
The I/O Ports have several modes of operation. Some modes can be defined using
PSDabel, 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, Address Input, and Peripheral I/O modes are the only
modes that must be defined before programming the device. All other modes can be
changed by the microcontroller at run-time. See Application Note 55 for more detail.
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.
