Section 8 I/O Ports
8.2.3
Mode 1
In mode 1, port 1 pins automatically function as address outputs. The port 1 pin functions are
shown in figure 8.2.
Modes 2 and 3 (EXPE = 1)
In modes 2 and 3 (when EXPE = 1), port 1 pins function as address outputs, PWM outputs, or
input 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 an address output or PWM output, and when cleared to 0,
as an input port.
The port 1 pin functions are shown in figure 8.3.
