Setting Vref in 12F675

Hi All.
When you use the command ADCIN, does this set Vref automatically to Vdd?

If Not, can someone please advise?

Thanks.

Peter

Hi Peter

No.
You must set the bits of ADCON0.
If bit 6=0 ...Vdd is reference.
If bit 6=1 ...AN1(GP1) is reference.(To do this you must set GP1 is analog)

You can find details on page 43 of 132 of Microchip Pic 12F629/675 data sheet.
