HV = High Voltage

XTAL = Crystal levels

Note 1:

Default peripheral input. Input can be moved to any other pin with the PPS input selection registers. See Register 12-2.

All pin outputs default to PORT latch data. Any pin can be selected as a digital peripheral output with the PPS output

selection registers. See Register 12-3.

These I2C functions are bidirectional. The output pin selections must be the same as the input pin selections.
