+        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
+        by clearing the ACIE bit in ACSR. Otherwise an interrupt can occur when
+        the bit is changed.

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.

+-----
+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.

+UART hardware flow control
+--------------------------
+(iWRAP4 User Guide 9.5)
+Hardware flow control is enabled by default and it should not be disabled unless mandatory, because without the hardware flow control the data transmission may not be reliable.
+If the hardware flow control is enabled from PS-keys, but no flow control is used, the following steps should be implemented in the hardware design:
+- CTS pin must be grounded
+- RTS pin must be left floating
