Description
P0.0 to P0.31
I/O
Port 0: Port 0 is a 32-bit bidirectional I/O port with individual
direction controls for each bit. The operation of port 0 pins
depends upon the pin function selected via the Pin Connect
Block.
Pins 26 and 31 of port 0 are not available.
TXD0 — Transmitter output for UART0.
PWM1 — Pulse Width Modulator output 1.
RXD0 — Receiver input for UART0.
