DIDR1 – Digital Input Disable Register 1
• Bit 7:2 – Reserved
These bits are unused bits in the Atmel
zero.
• Bit 1, 0 – AIN1D, AIN0D: AIN1, AIN0 Digital Input Disable
When this bit is written logic one, the digital input buffer on the AIN1/0 pin is disabled. The cor-
responding PIN Register bit will always read as zero when this bit is set. When an analog
signal is applied to the AIN1/0 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.
