Bits 15:0 – RESULT[15:0]: Result Conversion Value
These bits will hold up to a 16-bit ADC result, depending on the configuration.
These bits will hold up to a 16-bit ADC result, depending on the configuration.
In single-ended without averaging mode, the ADC conversion will produce a 12-bit result, which can be left- or
right-shifted, depending on the setting of CTRLB.LEFTADJ.
right-shifted, depending on the setting of CTRLB.LEFTADJ.
If the result is left-adjusted (CTRLB.LEFTADJ), the high byte of the result will be in bit position [15:8], while the
remaining 4 bits of the result will be placed in bit locations [7:4]. This can be used only if an 8-bit result is required;
i.e., one can read only the high byte of the entire 16-bit register.

i.e., one can read only the high byte of the entire 16-bit register.
If the result is not left-adjusted (CTRLB.LEFTADJ) and no oversampling is used, the result will be available in bit
locations [11:0], and the result is then 12 bits long.
