Port 1: Eight input/output pins. The data direction
of each pin can be selected in the port 1 data
direction register (P1DDR). These pins have built-in
MOS input pull-ups, and also have LED drive
capability.

Input/
output
Port 2: Eight input/output pins. The data direction
of each pin can be selected in the port 2 data
direction register (P2DDR). These pins have built-in
MOS input pull-ups, and also have LED drive
capability.

Port 3: Eight input/output pins. The data direction
of each pin can be selected in the port 3 data
direction register (P3DDR). These pins have built-in
MOS input pull-ups, and also have LED drive
capability.

of each pin can be selected in the port 4 data
direction register (P4DDR).
P52 to
P50
9 to 11
Input/
output
Port 5: Three input/output pins. The data direction
of each pin can be selected in the port 5 data
