P17 – P10 10 – 3 79 – 72 I/O Port 1: An 8-bit input/output port. The
I/O
direction of each bit is determined by the port 1
data direction register (P1DDR).
P24 – P20 15 – 11 4 – 1, I/O Port 2: A 5-bit input/output port. The
80
direction of each bit is determined by the port 2
data direction register (P2DDR).
P37 – P30 32 – 25 20 – 13 I/O Port 3: An 8-bit input/output port. The
direction of each bit is determined by the port 3
data direction register (P3DDR).
P47 – P40 40 – 33 28 – 21 I/O Port 4: An 8-bit input/output port. The
direction of each bit is determined by the port 4
data direction register (P4DDR). These pins
can drive LED indicators.
