Equation 1: FMAX = (6.0 MHz/V) (VDDAPPMIN - 2.0 V) + 4 MHz; VDDAPPMIN = 2.0V - 3.0V

Equation 2: FMAX = (10.0 MHz/V) (VDDAPPMIN - 3.0 V) + 10 MHz; VDDAPPMIN = 3.0V - 4.0V

Note 1: VDDAPPMIN is the minimum voltage of the PICmicro® device in the application.

Note 2: FMAX has a maximum frequency of 10MHz.
