Alternative Input Selection (only in PCM-Ports-MUX Mode 0 possible).
These bits determine the relationship between the physical pins and the
logical port numbers. The logical port numbers are used when programming
the switching functions.
Alternate Input Comparison 1.
0…input comparison of port 2 and 3 is disabled
1…the inputs of port 2 and 3 are compared
Alternate Input Comparison 0.
0…input comparison of port 0 and 1 is disabled
1…the inputs of port 0 and 1 are compared
