Analog-to-Digital Converter (ADC10) Module
3.8.3 ADC10 Result Low Register (ADRL)
This register holds the LSBs of the result. This register is updated each time a conversion completes.
Reading ADRH prevents the ADC10 from transferring subsequent conversion results into the result
registers until ADRL is read. If ADRL is not read until the after next conversion is completed, then the
intermediate conversion result will be lost. In 8-bit mode, there is no interlocking with ADRH.
3.8.4 ADC10 Clock Register (ADCLK)
This register selects the clock frequency for the ADC10 and the modes of operation.
ADLPC — ADC10 Low-Power Configuration Bit
48
ADLPC controls the speed and power configuration of the successive approximation converter. This
is used to optimize power consumption when higher sample rates are not required.
1 = Low-power configuration: The power is reduced at the expense of maximum clock speed.
0 = High-speed configuration
