Pin state at reset for default function: I = Input; O = Output; PU = internal pull-up enabled; IA = inactive, no pull-up/down enabled;
F = floating; floating pins, if not used, should be tied to ground or power to minimize power consumption.

5 V tolerant pad providing digital I/O functions with configurable pull-up/pull-down resistors, configurable hysteresis, and analog input.
When configured as a ADC input, digital section of the pad is disabled and the pin is not 5 V tolerant (see
Pad provides USB functions. It is designed in accordance with the USB specification, revision 2.0 (Full-speed and Low-speed mode
only).
When the system oscillator is not used, connect XTALIN and XTALOUT as follows: XTALIN can be left floating or can be grounded
(grounding is preferred to reduce susceptibility to noise). XTALOUT should be left floating.

Description
RESET — 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.
PIO0_0 — General purpose digital input/output pin.
PIO0_1 — General purpose digital input/output pin. A LOW level on this
pin during reset starts the ISP command handler or the USB device
enumeration (USB on LPC1342/43 only, see description of PIO0_3).
CLKOUT — Clock out pin.
CT32B0_MAT2 — Match output 2 for 32-bit timer 0.
USB_FTOGGLE — USB 1 ms Start-of-Frame signal (LPC1342/43 only).
PIO0_2 — General purpose digital input/output pin.
SSEL — Slave select for SSP.
CT16B0_CAP0 — Capture input 0 for 16-bit timer 0.
PIO0_3 — General purpose digital input/output pin. LPC1342/43 only: A
LOW level on this pin during reset starts the ISP command handler, a
HIGH level starts the USB device enumeration.
USB_VBUS — Monitors the presence of USB bus power (LPC1342/43
only).
PIO0_4 — General purpose digital input/output pin (open-drain).
SCL — I
