Digital Input Disable Register 0 – DIDR0
Digital Input Disable Register 1– DIDR1
• Bit 7:0 – ACMPMxD and ACMPxD: ACMPxMD, ACMPxD & APM0+Digital Input Disable
When this bit is written logic one, the digital input buffer on the corresponding Analog 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 one of these pins 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.
• Bit 3, 0: ACMPxMD, ACMPxD & APM0+ Digital Input Disable
When this bit is written logic one, the digital input buffer on the corresponding analog 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 one of these pins 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.
