IRQ Pin Timing

The MinInterruptPeriod is implemented as a hold off of IRQ latching per Figure 23 and Figure 24. In the first case the

MinInterruptPeriod is longer than the interval between sequential interrupt source events, thus it delays the IRQ from latching

until the MinInterruptPeriod has elapsed.

Figure 23. IRQ Timing Diagram - Case 1

In the second case the MinInterruptPeriod is shorter than the interval between sequential interrupt source events, thus the IRQ

latches as it normally would without additional delay.
