Description
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 — I
MAT2[0] — Match output for Timer 2, channel 0.
TXD3 — Transmitter output for UART3.
P4[29] — General purpose digital input/output pin.
TX_MCLK — I
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.
TDI — Test Data in for JTAG interface.
TMS — Test Mode Select for JTAG interface.
SWDIO — Serial wire debug data input/output.
TRST — Test Reset for JTAG interface.
TCK — Test Clock for JTAG interface.
SWDCLK — Serial wire clock.
RTCK — JTAG interface control signal.
RSTOUT — This is a 3.3 V pin. LOW on this pin indicates LPC1768/66/65/64
being in Reset state.
External reset input: A LOW on this pin resets the device, causing I/O ports and
peripherals to take on their default states, and processor execution to begin at
address 0. TTL with hysteresis, 5 V tolerant.
Input to the oscillator circuit and internal clock generator circuits.
Output from the oscillator amplifier.
Input to the RTC oscillator circuit.
Output from the RTC oscillator circuit.
ground: 0 V reference.
analog ground: 0 V reference. This should nominally be the same voltage as V
but should be isolated to minimize noise and error.
3.3 V supply voltage: This is the power supply voltage for the I/O ports.
3.3 V voltage regulator supply voltage: This is the supply voltage for the on-chip
voltage regulator only.
