Description
P2[10] — General purpose digital input/output pin. A LOW level on this
pin during reset starts the ISP command handler.
EINT0 — External interrupt 0 input.
NMI — Non-maskable interrupt input.
P2[11] — General purpose digital input/output pin.
EINT1 — External interrupt 1 input.
I2STX_CLK — Transmit Clock. It is driven by the master and received
by the slave. Corresponds to the signal SCK in the I2S-bus
specification. (LPC1769/68/67/66/65/63 only).
P2[12] — General purpose digital input/output pin.
EINT2 — External interrupt 2 input.
I2STX_WS — Transmit Word Select. It is driven by the master and
received by the slave. Corresponds to the signal WS in the I2S-bus
specification. (LPC1769/68/67/66/65/63 only).
P2[13] — General purpose digital input/output pin.
EINT3 — External interrupt 3 input.
I2STX_SDA — Transmit data. It is driven by the transmitter and read
by the receiver. Corresponds to the signal SD in the I2S-bus
specification. (LPC1769/68/67/66/65/63 only).
Port 3: Port 3 is a 32-bit I/O port with individual direction controls for
each bit. The operation of port 3 pins depends upon the pin function
selected via the pin connect block. Pins 0 through 24, and 27 through
31 of this port are not available.
P3[25] — General purpose digital input/output pin.
MAT0[0] — Match output for Timer 0, channel 0.
PWM1[2] — Pulse Width Modulator 1, output 2.
P3[26] — General purpose digital input/output pin.
STCLK — System tick timer clock input.
MAT0[1] — Match output for Timer 0, channel 1.
PWM1[3] — Pulse Width Modulator 1, output 3.
Port 4: Port 4 is a 32-bit I/O port with individual direction controls for
each bit. The operation of port 4 pins depends upon the pin function
selected via the pin connect block. Pins 0 through 27, 30, and 31 of this
port are not available.
P4[28] — General purpose digital input/output pin.
RX_MCLK — I2S receive master clock. (LPC1769/68/67/66/65 only).
MAT2[0] — Match output for Timer 2, channel 0.
TXD3 — Transmitter output for UART3.
P4[29] — General purpose digital input/output pin.
TX_MCLK — I2S transmit master clock. (LPC1769/68/67/66/65 only).
MAT2[1] — Match output for Timer 2, channel 1.
RXD3 — Receiver input for UART3.
TDO — Test Data out for JTAG interface.
SWO — Serial wire trace output.
