T
is the leading time between I-9048 receiving the input signal to the application receiving the interrupt
service.
Note
: If the interrupt signal is too short, the new status may be as same as old status. In that condition,
the interrupt service thread cannot identify which interrupt source is active. So the interrupt signal
must be hold long enough until the interrupt service thread is executed. This holding time is different
for different hardware & O.S.
