“PIN DECLARATIONS
“Declare all the pins that are used in the PSD3XX except Port A.
“Port A function (latched address out, I/O etc) are defined in the PSD Configuration.
“Pin numbers in this design are for the 44 pin PLCC package.
“*************************** Bus Interface signals declaration ***************************
“The following are multiplexed latched address inputs that are available
“as inputs to the PAD.
a15,a14,a13,a12,a11
pin 39,38,37,36,35;
“The following are bus control input signals from the 80C31
“In PSD Configuration, you need to select: 8-bit data, mux bus, and
“rd, wr, psen signal with active high ale signal

“program space enable
“address latch enable
“********************************* Port B pin declaration *********************************
“Port B pins (PB0–PB7) can be configured as:
“
1. Input or Output pin. No need to enter equations here for I/O pins. Declare the pin
“
such that the Fitter will not assign it for PAD output.
“
2. PAD output (chip select output). You need to write a logic equation for each of the
“
PAD output in the .abl file.
“Replace the reserved port pin name with your own signal name
