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 bidirectional 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.
Pins P0.24, P0.26 and P0.27 are not available.
P0.0 — General purpose input/output digital pin (GPIO).
TXD0 — Transmitter output for UART0.
PWM1 — Pulse Width Modulator output 1.
P0.1 — General purpose input/output digital pin (GPIO).
RXD0 — Receiver input for UART0.
PWM3 — Pulse Width Modulator output 3.
EINT0 — External interrupt 0 input.
P0.2 — General purpose input/output digital pin (GPIO).
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 (GPIO).
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.
P0.4 — General purpose input/output digital pin (GPIO).
SCK0 — Serial clock for SPI0. SPI clock output from master or input
to slave.
CAP0.1 — Capture input for Timer 0, channel 1.
AD0.6 — ADC 0, input 6.
P0.5 — General purpose input/output digital pin (GPIO).
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 — ADC 0, input 7.
P0.6 — General purpose input/output digital pin (GPIO).
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 — ADC 1, input 0. Available in LPC2144/46/48 only.
P0.7 — General purpose input/output digital pin (GPIO).
SSEL0 — Slave Select for SPI0. Selects the SPI interface as a slave.
PWM2 — Pulse Width Modulator output 2.
EINT2 — External interrupt 2 input.
