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.
