Description
Port 0: Port 0 is a 32-bit I/O port with individual direction controls for each bit.
A total of 31 pins of the Port 0 can be used as general purpose bidirectional
digital I/Os while P0.31 is an output only pin. The operation of port 0 pins
depends upon the pin function selected via the pin connect block.
P0.0 — General purpose input/output digital pin.
TXD0 — Transmitter output for UART0.
MAT3.1 — PWM output 1 for Timer 3.
P0.1 — General purpose input/output digital pin.
RXD0 — Receiver input for UART0.
MAT3.2 — PWM output 2 for Timer 3.
P0.2 — General purpose input/output digital pin. Output is open-drain.
SCL0 — I2C0 clock Input/output. Open-drain output (for I2C-bus compliance).
CAP0.0 — Capture input for Timer 0, channel 0.
P0.3 — General purpose input/output digital pin. Output is open-drain.
SDA0 — I2C0 data input/output. Open-drain output (for I2C-bus compliance).
MAT0.0 — PWM output for Timer 0, channel 0. Output is open-drain.
P0.4 — General purpose input/output digital pin.
SCK0 — Serial clock for SPI0. SPI clock output from master or input to slave.
CAP0.1 — Capture input for Timer 0, channel 1.
P0.5 — General purpose input/output digital pin.
MISO0 — Master In Slave Out for SPI0. Data input to SPI master or data
output from SPI slave.
MAT0.1 — PWM output for Timer 0, channel 1.
P0.6 — General purpose input/output digital pin.
MOSI0 — Master Out Slave In for SPI0. Data output from SPI master or data
input to SPI slave.
CAP0.2 — Capture input for Timer 0, channel 2.
P0.7 — General purpose input/output digital pin.
SSEL0 — Slave Select for SPI0. Selects the SPI interface as a slave.
MAT2.0 — PWM output for Timer 2, channel 0.
P0.8 — General purpose input/output digital pin.
TXD1 — Transmitter output for UART1.
MAT2.1 — PWM output for Timer 2, channel 1.
P0.9 — General purpose input/output digital pin.
RXD1 — Receiver input for UART1.
MAT2.2 — PWM output for Timer 2, channel 2.
P0.10 — General purpose input/output digital pin.
RTS1 — Request to Send output for UART1.
CAP1.0 — Capture input for Timer 1, channel 0.
AD0.3 — ADC 0, input 3.
