AD0ISEL: ADC0 Interrupt Source Select.
This bit selects which filter completion will set the AD0INT interrupt flag.
0: SINC3 filter.
1: FAST filter.
Unused: Read = 0b, Write = don’t care.
AD0VREF: ADC0 VREF Source Select.
0: ADC0 uses the internal VREF (2.5v). Setting this bit to ‘0’ enables the internal Voltage
Reference.
1: ADC0 uses an external VREF.
