Compare Value High Register (ADC1CVH)
This register holds the upper two bits of the 10-bit compare value. These bits are compared to the upper
two bits of the result following a conversion in 10-bit mode when the compare function is enabled.In 8-bit
operation, ADC1CVH is not used during compare.
14.4.6
Compare Value Low Register (ADC1CVL)
This register holds the lower 8 bits of the 10-bit compare value, or all 8 bits of the 8-bit compare value.
Bits ADCV7:ADCV0 are compared to the lower 8 bits of the result following a conversion in either 10-bit
or 8-bit mode.
14.4.7
Conguration Register (ADC1CFG)
ADC1CFG is used to select the mode of operation, clock source, clock divide, and congure for low power
or long sample time.
