Description

Port 0: Port 0 is a 32-bit bidirectional 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.

P0.0 — Port 0 bit 0.

TXD0 — Transmitter output for UART 0.

PWM1 — Pulse Width Modulator output 1.

P0.1 — Port 0 bit 1.

RXD0 — Receiver input for UART 0.

PWM3 — Pulse Width Modulator output 3.

P0.2 — Port 0 bit 2. The output is open-drain.

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

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

P0.3 — Port 0 bit 3. The output is open-drain.

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

MAT0.0 — Match output for Timer 0, channel 0. The output is open-drain.

P0.4 — Port 0 bit 4.

SCK — Serial clock for SPI/SSP[3]. Clock output from master or input to slave.

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

P0.5 — Port 0 bit 5.

MISO — Master In Slave Out for SPI/SSP[3]. Data input to SPI/SSP master or

data output from SPI/SSP slave.

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

P0.6 — Port 0 bit 6.

MOSI — Master Out Slave In for SPI/SSP[3]. Data output from SPI/SSP master

or data input to SPI/SSP slave.

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

P0.7 — Port 0 bit 7.

SSEL — Slave Select for SPI/SSP[3]. Selects the SPI/SSP interface as a slave.

PWM2 — Pulse Width Modulator output 2.

P0.8 — Port 0 bit 8.

TXD1 — Transmitter output for UART 1.

PWM4 — Pulse Width Modulator output 4.

P0.9 — Port 0 bit 9.

RXD1 — Receiver input for UART 1.

PWM6 — Pulse Width Modulator output 6.

P0.10 — Port 0 bit 10.

RTS1 — Request to Send output for UART 1.

CAP1.0 — Capture input for Timer 1, channel 0.
