bit for differential input channels) is required, it is sufficient to read ADCH. Otherwise,
ADCL must be read first, then ADCH.
The ADLAR bit in ADMUX, and the MUXn bits in ADMUX affect the way the result is
read from the registers. If ADLAR is set, the result is left adjusted. If ADLAR is cleared
(default), the result is right adjusted.

• Bits 7:0 – ADC7D:ADC0D: Digital Input Disable
When this bit is written logic one, the digital input buffer on the corresponding ADC pin
is disabled. The corresponding PIN Register bit will always read as zero when this bit is
set. When an analog signal is applied to the ADC7:0 pin and the digital input from this
pin is not needed, this bit should be written logic one to reduce power consumption in
the digital input buffer.
Reserved for future use.
• Bit 7:0 – ADC15D:ADC8D - Reserved Bits
This bit is reserved for future use. For ensuring compatibility with future devices, this bit
must be written to zero.
This register contains the calibration values of the reference voltage of the ADC. The
values are loaded from the fuse memory after power-up. They can be corrected by the
