Description
These pins make up Port B. These port pins are configurable, and
can have the following functions: (see Figure 6)
1. MCU I/O—in this mode, the direction of the pin is defined by its
direction bit, which resides in the direction register.
2. Chip select output—each of PB0-3 has four product terms
available per pin, while PB4-7 have 2 product terms each.
See Figure 4.
3. CMOS or open-drain.
4.
If your MCU is non-multiplexed, and the data bus width is
16 bits:
data bus input—connect your data bus (D8-D15) to these
pins. See Figure 3.

I/O
These pins make up Port C. These port pins are configurable, and
can have the following functions (see Figure 7):
1. PAD input—when configured as an input, a bit individually
becomes an address or a logic input, depending on your PSDsoft
design file. When declared as an address, the bit(s) can be latched
with ALE/AS.
2. PAD output—when configured as an output (i.e. there is an
equation written for it in your PSDsoft design file), there is one
product term available to it.

If your MCU is multiplexed:
These pins are the multiplexed, low-order address/data byte
(AD0-AD7). As inputs, address information is latched by the ALE/AS
signal and used internally by the PSD. The pins also serve as MCU
data bus inputs or outputs, depending on the MCU control signals
(RD, WR, etc.).
If your MCU is non-multiplexed:
These pins are the low-order address inputs (A0-A7)

If your MCU is multiplexed with a 16-bit data bus:
These pins are the multiplexed, high-order address/data byte
(AD8-AD15). As inputs, address information is latched by the
ALE/AS signal and used internally the PSD. The pins also
serve as MCU data bus inputs or outputs, depending on the MCU
control signals (RD, WR, etc.).
If your MCU is non-multiplexed or has a 8-bit data bus:
These pins are the high-order address inputs (A8-A15).
