Analog-to-Digital Converter (ADC10) Module
3.8.2 ADC10 Result High Register (ADRH)
This register holds the MSBs of the result and is updated each time a conversion completes. All other bits
read as 0s. 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, this register contains no interlocking with
ADRL.
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.
