1. In the formulas, T = system clock cycle and Tosc = oscillator clock cycle. For an operating frequency of 32MHz, T = 31.25ns. 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 56F8033/56F8023 internal reset stretching circuitry to extend this period to
2^21T.
