NOTE: 1. The direction of the Port A,B,C, and D pins are controlled by the Direction Register ORed with the
individual output enable product term (.oe) from the CPLD AND array.
2. Any of these three methods will enable JTAG pins on Port C.
9.4.2.1 MCU I/O Mode
In the MCU I/O Mode, the microcontroller uses the PSD8XXF ports to expand its own
I/O ports. By setting up the CSIOP space, the ports on the PSD8XXF are mapped into the
microcontroller address space. The addresses of the ports are listed in Table 7.
A port pin can be put into MCU I/O mode by writing a ‘0’ to the corresponding bit in the
Control Register. The MCU I/O direction may be changed by writing to the corresponding
bit in the Direction Register, or by the output enable product term. See the subsection on
the Direction Register in the “Port Registers” section. When the pin is configured as an
output, the content of the Data Out Register drives the pin. When configured as an input,
the microcontroller can read the port input through the Data In buffer. See Figure 22.
Ports C and D do not have Control Registers, and are in MCU I/O mode by default. They
can be used for PLD I/O if equation are written for them in PSDabel.
9.4.2.2 PLD I/O Mode
The PLD I/O Mode uses a port as an input to the CPLD’s Input Micro
Cells, and/or as an
output from the CPLD’s Output Micro
Cells. The output can be tri-stated with a control
signal. This output enable control signal can be defined by a product term from the PLD, or
by setting the corresponding bit in the Direction Register to ‘0’. The corresponding bit in the
Direction Register must not be set to ‘1’ if the pin is defined as a PLD input pin in PSDabel.
The PLD I/O Mode is specified in PSDabel by declaring the port pins, and then writing an
equation assigning the PLD I/O to a port.
