“PIN DECLARATIONS
“Declare all the pins that are used in the PSD4XX/5XX.
“********************* Bus Interface signals declaration *********************
“The following are multiplexed latched address inputs that are available as inputs
“to the ZPLD.
a9,a8,a1,a0
a15,a14,a13,a12,a11,a10
pin 67,68,8,9;
pin 61,62,63,64,65,66;
“The following are bus control input signals from the 80C31
“In PSDConfiguration, you need to select:8-bit data, mux bus, and
“rd, wr, psen signal with active high ale.
rd

psen

pin 41;
pin 29;
pin 38;
pin 37;
pin 40;
pin 39;
pin 42;
“read line
“write line
“program space enable
“address latch enable
“reset input, active low
“PSD chip select, grounded if pin is not used
“clock input, optional
“**************************** Port A, B, C, D, E pin declaration ****************************
“The following are I/O Port pin assignments. Port functions that need
“to be declared here are:
“
1. latched address output a0-a7 (Port C or D)
2. other address inputs: a2-a7 (Port A)
“
3. MCU inputs/outputs
“
4. GPLD inputs/outputs
“Your software needs to set up the appropriate registers to enable Port functions such as
“the latched address and MCU I/O (see I/O section in the PSD Data Book for instructions).
“No equations are required if the pins are declared for non-GPLD function.
“If GPLD output is an internal feedback, you can assign it as a ‘node’, where the node
“number is the same as the pin number.
“For PLD pins: you may want the PSD Fitter to assign the pins for you for complex logic
“functions. In that case you need only to declare the PLD signal as ‘pin’ and omit
“the pin number.
