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

In left justified sign mode the ADRH0 holds the eight MSBs with the MSB complemented, and the ADRL0
holds the two least significant bits (LSBs), of the 10-bit result. The 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
