• 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:
ACMPN1, ACMPN0, ACMPN2, ACMP2 and ACMPN3 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.
