trigger signal. If ADEN in ADCSRA is set, this will start a conversion. Switching to Free Running

mode (ADTS[2:0]=0) will not cause a trigger event, even if the ADC Interrupt Flag is set

DIDR0 – Digital Input Disable Register 0

• Bit 7:0 – ADC7D..ADC0D: ADC7..0 Digital Input Disable

When this bit is written logic one, the digital input buffer on the corresponding ADC pin is dis-

abled. 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.
