The MinInterruptPeriod is implemented as a hold off of IRQ latching per
MinInterruptPeriod is longer than the interval between sequential interrupt source events, thus it delays the IRQ from latching
until the MinInterruptPeriod has elapsed.
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.
