PA7–PA0 is an 8-bit I/O port. When CPAF2 = 0 it can be configured
separately as an I/O or lower-order latched address line. When
configured as an I/O (CPAF1 = 0), the direction of the pin is defined
by its direction bit, which resides in the direction register. If a pin is
an I/O output, its data bit (which resides in the data register) comes
out. When it is configured as a low-order address line (CPAF1 =1),
A7–A0 can be made the corresponding output through this port
(e.g., PA6 can be configured to be the A6 address line).

PB0
PB7–PB0 is an 8-bit port for which each bit can be configured as an
I/O (CPBF = 1) or chip-select output (CPBF = 0). When configured
as an I/O, the direction of the pin is defined by its direction bit, which
resides in the direction register. If a pin is an I/O output, its data
(which resides in the data register) comes out. When configured
as a chip-select output, CS0–CS3 are a function of up to four
product terms of the inputs to the PAD B; CS4–CS7 then are each a
function of up to two product terms.
I/O
This is a 3-bit port for which each bit is configurable as a PAD A
and B input or output. When configured as an input (CPCF = 0),a bit
individually becomes an address (CATD = 1) or a logic input
(CATD = 0). The addresses can be latched with ALE (CADDHLT = 1)
or be transparent inputs to the PADs (CADDHLT = 0). When a pin is
configured as an output (CPCF = 1), it is a function of one product
term of all PAD inputs. See Figure 6.

These pins are the multiplexed low-order address/data byte.
After ALE latches the addresses, these pins input or output data,
depending on the settings of the RD/E, WR/V
PP
or R/W, and
PSEN pins.
