Description
Port 0: Port 0 is a 32-bit I/O port with individual direction controls for each bit.
Total of 31 pins of the Port 0 can be used as a general purpose bidirectional
digital I/Os while P0.31 is output only pin. The operation of port 0 pins
depends upon the pin function selected via the pin connect block.
Pins P0.24, P0.26 and P0.27 are not available.
P0.0 — General purpose input/output digital pin (GPIO).
TXD0 — Transmitter output for UART0.
PWM1 — Pulse Width Modulator output 1.
P0.1 — General purpose input/output digital pin (GPIO).
RXD0 — Receiver input for UART0.
PWM3 — Pulse Width Modulator output 3.
EINT0 — External interrupt 0 input
P0.2 — General purpose input/output digital pin (GPIO).
SCL0 — I2C0 clock input/output. Open-drain output (for I2C-bus compliance).
CAP0.0 — Capture input for Timer 0, channel 0.
