1.
In the formulas, T = clock cycle. For an operating frequency of 60MHz, T = 16.67ns. At 8MHz (used during Reset and
Stop modes), T = 125ns.

4.
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.
