Section 9 I/O Ports
9.5
Port 5 is an 8-bit I/O port. Port 5 pins also function as interrupt input pins, the PWMX output pin,
SCI_0, SCI_1, and SCI_2 input/output pins. Port 5 has the following registers.
9.5.1
The individual bits of P5DDR specify input or output for the pins of port 5.

If port 5 pins are specified for use as the general
I/O port, the corresponding port 5 pins are output
ports when the P5DDR bits are set to 1, and input
ports when cleared to 0.
