Description
P2[8] — General purpose digital input/output pin.
TD2 — CAN2 transmitter output. (LPC1758/56 only).
TXD2 — Transmitter output for UART2.
P2[9] — General purpose digital input/output pin.
USB_CONNECT — Signal used to switch an external 1.5 kΩ resistor under
software control. Used with the SoftConnect USB feature.
RXD2 — Receiver input for UART2.
P2[10] — General purpose digital input/output pin.
Note: LOW on this pin while RESET is LOW forces on-chip bootloader to take
over control of the part after a reset.
EINT0 — External interrupt 0 input.
NMI — Non-maskable interrupt input.
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. Some port pins are not available on the LQFP80 package.
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.
RSTOUT — This is a 3.3 V pin. LOW on this pin indicates LPC1758/56/54/52/51
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.
