Description
Port 0: Port 0 is a 32-bit I/O port with individual direction
controls for each bit. A total of 31 pins of the Port 0 can be
used as general purpose bidirectional digital I/Os while P0.31
is an output only pin. The operation of port 0 pins depends
upon the pin function selected via the pin connect block.
P0.0 — General purpose Input/output digital pin (GPIO).
TXD0 — Transmitter output for UART0.
MAT3.1 — PWM output 1 for Timer 3.
P0.1 — General purpose Input/output digital pin (GPIO).
RXD0 — Receiver input for UART0.
MAT3.2 — PWM output 2 for Timer 3.
