Pin Configuration
Port 0: Port 0 is a 32-bit bi-directional 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.
P0.0 TxD0 Transmitter output for UART0.
PWM1 Pulse Width Modulator output 1.
P0.1 RxD0 Receiver input for UART0.
PWM3 Pulse Width Modulator output 3.
EINT0 External interrupt 0 input.
