Pins can be used as digital inputs when USB is not enabled.

This bit field is contained in the OSCCON register.

This bit field is contained in the OSCTRM register.

USB PLL UFIN requirements: 4 MHz.

This bit field is contained in the DEVCFG2 register.

A 48 MHz clock is required for proper USB operation.

Pins can be used as GPIO when the USB module is disabled.
