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.
2. Parameters listed are guaranteed by design.
3. During Power-On Reset, it is possible to use the device’s internal reset stretching circuitry to extend this period to 221T.
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.
5. The interrupt instruction fetch is visible on the pins only in Mode 3.
