ADC start bit
0 = Force to zero
1 = Start ADC, then after one cycle, the bit is cleared to '0.'
ADC Status Bit
0 = ADC conversion is not completed
1 = ADC conversion is completed. The bit can also be cleared with software.
Reserved
ADC conversion reference clock enable
0 = ADC reference clock is disabled (default)
1 = ADC reference clock is enabled
ADC reference clock prescaler
Only three Prescaler values are allowed:
ADCPS[2:0] = 0, for f
f
ADCPS[2:0] = 1, for f
f
ADCPS[2:0] = 2, for f
is f
