The ADC data register 0 consist of a pair of 8-bit registers: high byte
(ADRH0), and low byte (ADRL0). This pair form a 16-bit register to store
the 10-bit ADC result for the selected ADC result justification mode.
In 8-bit truncated mode, the ADRL0 holds the eight most significant bits
(MSBs) of the 10-bit result. The ADRL0 is updated each time an ADC
conversion completes. In 8-bit truncated mode, ADRL0 contains no
interlocking with ADRH0. (See
Bit Truncated
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.
