23.2.1 Digital Input Disable Register 1 – DIDR1
Bit 0 – AIN0D: AIN0 Digital Input Disable
When this bit is written logic one, the digital input buffer on the AIN0 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 AIN0 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.
