In Microcontroller mode:
FMAX = (9.55 MHz/V) (VDDAPPMIN – 2.0V) + 4 MHz, if VDDAPPMIN  4.2V;
F
MAX = 25 MHz, if VDDAPPMIN > 4.2V.
In modes other than Microcontroller mode:
F
MAX = (5.45 MHz/V) (VDDAPPMIN – 2.0V) + 4 MHz, if VDDAPPMIN  4.2V;
F
MAX = 16 MHz, if VDDAPPMIN > 4.2V.
Note: V
DDAPPMIN is the minimum voltage of the PIC
