Digital Input Disable Register 0 – DIDR0
Digital Input Disable Register 1– DIDR1
AC3O bit is directly the output of the Analog comparator 2.
Set when the output of the comparator is high.
Cleared when the output comparator is low.
• Bit 2– AC2O: Analog Comparator 2 Output Bit
AC2O bit is directly the output of the Analog comparator 2.
Set when the output of the comparator is high.
Cleared when the output comparator is low.
• Bit 1– AC1O: Analog Comparator 1 Output Bit
AC1O bit is directly the output of the Analog comparator 1.
Set when the output of the comparator is high.
Cleared when the output comparator is low.
• Bit 0– AC0O: Analog Comparator 0 Output Bit
AC0O bit is directly the output of the Analog comparator 0.
Set when the output of the comparator is high.
Cleared when the output comparator is low.
• Bit 6, 5, 3, 2, 0 – ACMPN1D, ACMPN0D, ACMPN2D, ACMP2D and ACMPN3D:
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.
• 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.
