ADCF
: AD Conversion Enable Signal.
: AD Conversion Request Bit.
: Set or Cleared by H/W.
: ADC Interrupt Flag.
This bit must be set again for every sample conversion.
You should clear ADCF bit in the ADC interrupt routine.
Set or Cleared by S/W.
Set by S/W and Cleared by H/W.
Cleared when the conversion is started.
Set when the conversion is finished.
