"1". Any edges that might arrive at pins labelled with an "X" are ignored.
Only the change in state of a pin whose edge is set to "1" in the parameter
<iIrqArg>
can issue an interrupt.
The interrupt event is evaluated with the function
meIOIrqWait().
We rec-
ommend using what is known as the "extended format" to obtain detailed
information about the triggering edge.
4.2.2
Bit-Pattern Compare
In the “bit-pattern compare” mode, the bit-pattern of digital inputs can be
monitored for equality or inequality. The compare bit-pattern of the corre-
sponding subdevice is used as reference. If the state changes from une-
qual to equal or from equal to unequal, an interrupt is generated (see pic-
ture 17 on page 28).
