DIDR0 – Digital Input Disable Register 0
• Bits 2:1 – ADC2D, ADC1D: ADC[2:1] Digital input buffer disable
When this bit is written logic one, the digital input buffer on the AIN1/0 pin is disabled. The corre-
sponding PIN Register bit will always read as zero when this bit is set. When used as an analog
input but not required as a digital input the power consumption in the digital input buffer can be
reduced by writing this bit to logic one.
