DIDR0 – Digital Input Disable Register 0
Table 18-7.
• Bits 7..0 – ADC7D..ADC0D: ADC7..0 Digital Input Disable
When this bit is written logical 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 logical one to reduce power consumption in the digital input buffer.
