Description
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.
TxD0 — Transmitter output for UART0.
PWM1 — Pulse Width Modulator output 1.
RxD0 — Receiver input for UART0.
PWM3 — Pulse Width Modulator output 3.
EINT0 — External interrupt 0 input
SCL — I2C clock input/output. Open drain output (for I2C compliance).
CAP0.0 — Capture input for Timer0, channel 0.
SDA — I2C data input/output. Open drain output (for I2C compliance).
MAT0.0 — Match output for Timer0, channel 0.
EINT1 — External interrupt 1 input.
SCK0 — Serial clock for SPI0. SPI clock output from master or input to slave.
CAP0.1 — Capture input for Timer0, channel 1.
MISO0 — Master In Slave OUT for SPI0. Data input to SPI master or data
output from SPI slave.
MAT0.1 — Match output for Timer0, channel 1.
MOSI0 — Master Out Slave In for SPI0. Data output from SPI master or data
input to SPI slave.
CAP0.2 — Capture input for Timer0, channel 2.
SSEL0 — Slave Select for SPI0. Selects the SPI interface as a slave.
PWM2 — Pulse Width Modulator output 2.
EINT2 — External interrupt 2 input.
TxD1 — Transmitter output for UART1.
PWM4 — Pulse Width Modulator output 4.
RxD1 — Receiver input for UART1.
PWM6 — Pulse Width Modulator output 6.
EINT3 — External interrupt 3 input.
RTS1 — Request to Send output for UART1.
CAP1.0 — Capture input for Timer1, channel 0.
CTS1 — Clear to Send input for UART1.
