Type Description
P0[0] to P0[31]
I/O
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.
