Description
Port 0: Port 0 is a 32-bit I/O port with individual direction controls for each bit.
Total of 29 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 — I
CAP0[0] — Capture input for Timer 0, channel 0.
P0[3] — General purpose input/output digital pin (GPIO).
SDA0 — I
