When configured as a ADC input, digital section of the pad is disabled and the pin is not 5 V tolerant (see
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
Port 0 — Port 0 is a 12-bit I/O port with individual direction and
function controls for each bit. The operation of port 0 pins depends
on the function selected through the IOCONFIG register block.
RESET — External reset input with 20 ns glitch filter. A LOW-going
pulse as short as 50 ns 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 with 10 ns
glitch filter.
PIO0_1 — General purpose digital input/output pin. A LOW level
on this pin during reset starts the ISP command handler.
CLKOUT — Clockout pin.
CT32B0_MAT2 — Match output 2 for 32-bit timer 0.
PIO0_2 — General purpose digital input/output pin.
SSEL0 — Slave Select for SPI0.
CT16B0_CAP0 — Capture input 0 for 16-bit timer 0.
PIO0_3 — General purpose digital input/output pin.
PIO0_4 — General purpose digital input/output pin (open-drain).
SCL — I
