Description

P0[0] to P0[31]

I/O

Port 0: Port 0 is a 32-bit 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]/RD1/TXD/

SDA1

66[1]

I/O

P0[0] — General purpose digital input/output pin.

RD1 — CAN1 receiver input. (LPC2378 only)

TXD3 — Transmitter output for UART3.

I/O

SDA1 — I2C1 data input/output (this is not an open-drain pin).

P0[1]/TD1/RXD3/

SCL1

67[1]

I/O

P0[1] — General purpose digital input/output pin.

TD1 — CAN1 transmitter output. (LPC2378 only)

RXD3 — Receiver input for UART3.

I/O

SCL1 — I2C1 clock input/output (this is not an open-drain pin).

P0[2]/TXD0

141[1]

I/O

P0[2] — General purpose digital input/output pin.

TXD0 — Transmitter output for UART0.

P0[3]/RXD0

142[1]

I/O

P0[3] — General purpose digital input/output pin.

RXD0 — Receiver input for UART0.

P0[4]/

I2SRX_CLK/

RD2/CAP2[0]

116[1]

I/O

P0[4] — General purpose digital input/output pin.

I/O

I2SRX_CLK — Receive Clock. It is driven by the master and received by the slave.

Corresponds to the signal SCK in the

I2S-bus speciﬁcation.

RD2 — CAN2 receiver input. (LPC2378 only)

CAP2[0] — Capture input for Timer 2, channel 0.
