NOTES:
1. Port C pins can be individually configured as inputs
or
outputs, but
not
both. Pins can be individually
configured as address or logic and latched or transparent, except for the 3X1 devices, which must be
set to all address or all logic.
2. PSDsoft sets this configuration prior to run-time based on your PSDsoft design file.
Figure 7. Port C (PC0-PC2) Pin Structure
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 PAD B, and can be used in
any or all PAD equations.
2) A logic input is 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.
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.

10.5 ALE/AS Input Pin
The ALE/AS pin may be used as a generic logic input signal to the PADs if a
non-multiplexed MCU configuration is chosen in PSDsoft.
