In left justified mode the ADRH0 holds the eight most significant bits
(MSBs), 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
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
