Function
Internal/external start of conversion.
When set, the external start of conversion by P4.0 / ADST is enabled
Busy flag.
This flag indicates whether a conversion is in progress (BSY = 1). The flag
is cleared by hardware when the conversion is finished.
A/D Conversion mode.
When set, a continuous conversion is selected.
If cleared, the converter stops after one conversion.
Select 8 input channels of the ADC.
Bits MX0 to MX2 can be written or read either in ADCON0 or in ADCON1
