Section 8 I/O Ports
Modes 2 and 3 (EXPE = 0): In modes 2 and 3 (when EXPE = 0), port 1 pins function as PWM
outputs or I/O ports, and input or output can be specified on a bit-by-bit basis. When a bit in
P1DDR is set to 1, the corresponding pin functions as a PWM output or output port, and when
cleared to 0, as an input port.
The port 1 pin functions are shown in figure 8.4.
