Analog-to-Digital Converter (ADC)
18.9.2 ADC Data Register High
Technical Data
322
In left justified mode, this 8-bit result register holds the eight MSBs of the
10-bit result. This register is updated each time an ADC single channel
conversion completes. Reading ADRH latches the contents of ADRL
until ADRL is read. Until ADRL is read, all subsequent ADC results will
be lost.

In right justified mode, this 8-bit result register holds the two MSBs of the
10-bit result. All other bits read as 0. This register is updated each time
a single channel ADC conversion completes. Reading ADRH latches the
contents of ADRL until ADRL is read. Until ADRL is read, all subsequent
ADC results will be lost.
