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.

reset the chip and wake up from Deep power-down mode. An external pull-up resistor is required on this pin for the Deep power-down
mode.

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
input glitch filter.
Pad provides USB functions. It is designed in accordance with the USB specification, revision 2.0 (Full-speed and Low-speed mode
only). This pad is not 5 V tolerant.
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.
When the system oscillator is not used, connect XTALIN and XTALOUT as follows: XTALIN can be left floating or can be grounded

To select a port pin for a peripheral function from
port pin’s IOCON register with this function. The user must ensure that the assignment of
a function to a port pin is unambiguous. Only the debug functions for JTAG and SWD are
selected by default in their corresponding IOCON registers. All other functions must be
programmed in the IOCON block before they can be used. For details see the LPC11U1x
user manual.
