Comparing Input Patterns
In addition to the Event Detection Mode, it is also possible to detect a complete input pattern
automatically. In this mode the input vector is continuously compared with the content of the
Input Pattern Compare Register. In the case of a match a flag is set within the Input Status Reg-
ister. Single inputs can also be masked out individually in the Input Pattern Mask Register.

Input event mask bits
Note ...
A set bit means that the corresponding input is masked out for pattern recogni-
tion. There is no special enable for pattern recognition since it is switched off by
default as long as all mask bits are set.

Input pattern compare bits
Note ...
This register stores the input compare data. A compare match is reported within
the Input Status Register (Bit 31). To reset a compare match, the status flag
must be reset by writing a "1" to it and also the match condition must cease.
