+        When this bit is written logic one, the power to the Analog Comparator is
+        switched off. This bit can be set at any time to turn off the Analog
+        Comparator. This will reduce power consumption in Active and Idle mode.
+        When changing the ACD bit, the Analog Comparator Interrupt must be disabled

When an analog signal is applied to the AIN1/0 pin 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.

+Notes
+-----
+Many ADB keyboards has no discrimination between right modifier and left one,
+you will always see left control even if you press right control key.
+Apple Extended Keyboard and Apple Extended Keyboard II are the examples.
+Though ADB protocol itsef has the ability of distinction between right and left.
+And most ADB keyboard has no NKRO functionality, though ADB protocol itsef has that.
