2.
In the formulas, T = clock cycle. For an operating frequency of 80MHz, T = 12.5ns.
Circuit stabilization delay is required during reset when using an external clock or crystal oscillator in two cases:
After power-on reset
When recovering from Stop state
The minimum is specified for the duration of an edge-sensitive IRQA interrupt required to recover from the Stop state.
This is not the minimum required so that the IRQA interrupt is accepted.
4.
The interrupt instruction fetch is visible on the pins only in Mode 3.
5.
Parameters listed are guaranteed by design.
