4.4.6 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.
4.4.7 Writing Output Data
Table 4-10: Input Pattern Mask Register
BITS TYPE DEFAULT FUNCTION
31-16 r/w 0 Not used
15 - 0 r/w 1 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.
Table 4-11: Input Pattern Compare Register
BITS TYPE DEFAULT FUNCTION
31-16 r/w 0 Not used
15 - 0 r/w 1 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.
Table 4-12: Output Data Register
BITS TYPE DEFAULT FUNCTION
31-8 r/w 0 Reserved
7-0 r/w 0 Data, 8-bit digit
Note ...
Output data is 8 bit; this register is read/write enable.
