Notes:

1. MUX4 does not affect Analog Comparator input selection.
2. Pin change interrupt on PA6 and PA7 is disabled if the Analog Comparator is

enabled. This happens regardless of whether AIN1 or AIN0 has been replaced as
inputs to the Analog Comparator.

3. The MUX3...0 selections go into effect after one clock cycle delay.
