Analog-to-Digital Converter (ADC)
In right justified mode the ADRH0 holds the two MSBs, and the ADRL0 holds the eight least significant
bits (LSBs), of the 10-bit result. ADRH0 and ADRL0 are updated each time a single channel ADC
conversion completes. Reading ADRH0 latches the contents of ADRL0. Until ADRL0 is read all
subsequent ADC results will be lost. (See
