8197C–AVR–05/11

ATtiny261A/461A/861A

applied to the AREF 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.

14.2.4 DIDR1 – Digital Input Disable Register 1

• Bits 7:4 – ADC10D:ADC7D: ADC[10:7] 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 ADC[10:7] 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.
