Port 0. This is a high-impedance, input-only port. Port 0 pins
should not be left floating.
These pins may individually be used as analog inputs
(ACH x ) or digital inputs (P0. x ). While it is possible for the pins
to function simultaneously as analog and digital inputs, this is
not recommended because reading port 0 while a conversion
is in process can produce unreliable conversion results.

converter to function.
Port 1. This is a 4-bit, bidirectional, standard I/O port that is
multiplexed with individually selectable special-function
signals. (Used as PBUS.15:12 in Auto-programming Mode.)
Port 2. This is an 8-bit, bidirectional, standard I/O port that is
multiplexed with individually selectable special-function
signals. P2.6 is multiplexed with a special test mode function.
To prevent accidental entry into test modes, always configure
P2.6 as an output.
Port 3. This is an 8-bit, bidirectional, memory-mapped I/O
port with open-drain outputs. The pins are shared with the
multiplexed address/data bus, which has complementary
drivers.
In programming modes, port 3 serves as the low byte of the
programming bus (PBUS).
Port 4. This is an 8-bit, bidirectional, memory-mapped I/O
port with open-drain outputs. The pins are shared with the
multiplexed address/data bus, which has complementary
drivers.
In programming modes, port 4 serves as the high byte of the
programming bus (PBUS).
Port 5. This is an 8-bit, bidirectional, standard I/O port that is
multiplexed with individually selectable control signals.
Because P5.4 is multiplexed with the ONCE# function,
always configure it as an output to prevent accidental entry
into ONCE mode.
