Serves as Deep-sleep wake-up input pin to the start logic independently of selected pin function (see the LPC111x/11C1x user manual).

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
5 V tolerant digital I/O pad without pull-up/pull-down resistors.
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
CAN_TXD — C_CAN transmit data output.
Supply voltage to the internal regulator, the external rail, and the ADC. Also
used as the ADC reference voltage.
Input to the oscillator circuit and internal clock generator circuits. Input
voltage must not exceed 1.8 V.
Output from the oscillator amplifier.
Ground.
