Bit 5 – ACMP0D: ACMP0 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 2 – ACMP1PD: ACMP1P 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 2 – ACMP2D: ACMP2 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 1 – ACMP3PD: ACMP3P 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 0 – ACMPN3D: 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.
