NOTES:
7. IIOFx is an asynchronous input and can be asserted at any point during a clock cycle. If the specified timings are met, the exact
sequence shown occurs; otherwise, an additional delay of one clock cycle can occur.
8. Edge-triggered interrupts require a setup of time (1) and a minimum duration of P. No maximum duration limit exists.
9. Level-triggered interrupts require interrupt pulse duration of at least 1P wide (P = one H1 period) to ensure that the interrupt is seen.
It must be less than 2P wide to ensure that it is responded to only once. Recommended pulse duration is 1.5P.
