15.3.5
In 12-bit mode, the ADCCVH register holds the upper four bits of the 12-bit compare value. These bits are
compared to the upper four bits of the result following a conversion in 12-bit mode when the compare
function is enabled.
In 10-bit mode, the ADCCVH register holds the upper two bits of the 10-bit compare value (ADCV9 –
ADCV8). These bits are compared to the upper two bits of the result following a conversion in 10-bit mode
when the compare function is enabled.
In 8-bit mode, ADCCVH is not used during compare.
15.3.6
This register holds the lower 8 bits of the 12-bit or 10-bit compare value, or all 8 bits of the 8-bit compare
value. Bits ADCV7:ADCV0 are compared to the lower 8 bits of the result following a conversion in 12-bit,
10-bit or 8-bit mode.
15.3.7
ADCCFG is used to select the mode of operation, clock source, clock divide, and configure for low power
or long sample time.
