DIDR1 – Digital Input Disable Register 1
• Bit 5, 2, 1: ACMP0D, ACMP1PD, ACMP3PD:
When this bit is written logic one, the digital input buffer on the corresponding analog 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 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.
