the intermediate conversion data is lost. In 8-bit mode, there is no interlocking with ADCRH. If the MODE
bits are changed, any data in ADCRL becomes invalid.
9.3.5
In 10-bit mode, the ADCCVH register holds the upper two bits of the 10-bit compare value (ADCV[9:8]).
When the compare function is enabled, these bits are compared to the upper two bits of the result following
a conversion in 10-bit mode.
In 8-bit operation, ADCCVH is not used during compare.
9.3.6
The ADCCVL register holds the lower eight bits of the 10-bit compare value or all eight bits of the 8-bit
compare value. When the compare function is enabled, bits ADCV[7:0] are compared to the lower eight
bits of the result following a conversion in 10-bit or 8-bit mode.
9.3.7
ADCCFG selects the mode of operation, clock source, clock divide, and configures for low power and long
sample time.
