Description
Port 0: Port 0 is a 32-bit I/O port with individual direction controls for each bit.
Total of 31 pins of the Port 0 can be used as a general purpose bi-directional
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.
Pin P0.24 is 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
SCL0 — I2C0 clock input/output. Open drain output (for I2C-bus compliance).
CAP0.0 — Capture input for Timer 0, channel 0.
SDA0 — I2C0 data input/output. Open drain output (for I2C-bus compliance).
MAT0.0 — Match output for Timer 0, 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 Timer 0, channel 0.
AD0.6 — A/D converter 0, input 6. This analog input is always connected to
its pin.
MISO0 — Master In Slave OUT for SPI0. Data input to SPI master or data
output from SPI slave.
MAT0.1 — Match output for Timer 0, channel 1.
AD0.7 — A/D converter 0, input 7. This analog input is always connected to
its 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.
AD1.0 — A/D converter 1, input 0. This analog input is always connected to
its pin. Available in LPC2138 only.
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.
AD1.1 — A/D converter 1, input 1. This analog input is always connected to
its pin. Available in LPC2138 only.
RXD1 — Receiver input for UART1.
PWM6 — Pulse Width Modulator output 6.
EINT3 — External interrupt 3 input.
