I/O

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.

I/O

P0.0 — Port 0 bit 0.

TxD0 — Transmitter output for UART 0.

PWM1 — Pulse Width Modulator output 1.

I/O

P0.1 — Port 0 bit 1.

RxD0 — Receiver input for UART 0.

PWM3 — Pulse Width Modulator output 3.

I/O

P0.2 — Port 0 bit 2.

I/O

SCL — I2C clock input/output. Open drain output (for I2C compliance).

CAP0.0 — Capture input for Timer 0, channel 0.

I/O

P0.3 — Port 0 bit 3.

I/O

SDA — I2C data input/output. Open drain output (for I2C compliance).

MAT0.0 — Match output for Timer 0, channel 0.

I/O

P0.4 — Port 0 bit 4.

I/O

SCK — Serial clock. SPI clock output from master or input to slave.

CAP0.1 — Capture input for Timer 0, channel 1.

I/O

P0.5 — Port 0 bit 5.

I/O

MISO — Master In Slave Out. Data input to SPI master or data output from

SPI slave.

MAT0.1 — Match output for Timer 0, channel 1.

I/O

P0.6 — Port 0 bit 6.

I/O

MOSI — Master Out Slave In. Data output from SPI master or data input to

SPI slave.

CAP0.2 — Capture input for Timer 0, channel 2.

I/O

P0.7 — Port 0 bit 7.

SSEL — Slave Select. Selects the SPI interface as a slave.

PWM2 — Pulse Width Modulator output 2.

I/O

P0.8 — Port 0 bit 8.

TxD1 — Transmitter output for UART 1.

PWM4 — Pulse Width Modulator output 4.
