10.4 Port C (PC0-PC2)
Each pin of Port C (Figure 7) can be configured as an input to PAD A and PAD B, or as an
output from PAD B. As inputs, the pins are referenced as A16-A18. Although the pins are
given this reference, they can be used for any address or logic input. [For example, A8-A10
could be connected to those pins to improve the resolution (boundaries) of CS0-CS7 to
256 bytes.] How they are defined in the PSDsoft design file determines:
Whether they are address or logic inputs
Whether the input is transparent or latched by the trailing edge of ALE/AS.
Notes:
1) If the inputs are addresses, they are routed to PAD A and B, and can be used in any or
all PAD equations.
2) If the inputs are logic, they are routed to PAD B and can be used for Boolean equations
that are implemented in any or all of the CS0-CS10 PAD B outputs.
3) If Port C pins are configured as inputs, they can not be individually configured as
address or logic and latched or transparent. They must be configured as a group to be
address or logic and latched or transparent.
Alternately, PC0-PC2 can become CS8-CS10 outputs, respectively, providing the user with
more external chip-select PAD outputs. Each of the signals (CS8-CS10) is comprised of
one product term.

NOTES:
1. Port C pins can be individually configured as inputs

outputs, but
not
both.
2. PSDsoft sets this configuration prior to run-time based on your PSDsoft design file.
