DIDR0 – Digital Input Disable Register 0
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
Table 15-6.
• Bits 7:0 – ADC7D:ADC0D : ADC[7:0] Digital Input Disable
When a 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 ADC[7:0] 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.
