1. In the formulas, T = clock cycle. For an operating frequency of 60MHz, T = 16.67ns. At 8MHz (used during Reset and Stop
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 2
4. The minimum is specified for the duration of an edge-sensitive IRQA interrupt required to recover from the Stop state. This
5. The interrupt instruction fetch is visible on the pins only in Mode 3.
