For example, suppose a 10 MHz crystal is being used
with “XT with PLL” as the selected oscillator mode. If
PLLPRE<4:0> = 0, then N1 = 2. This yields a VCO input
of 10/2 = 5 MHz, which is within the acceptable range of
0.8-8 MHz. If PLLDIV<8:0> = 0x1E, then M = 32. This
yields a VCO output of 5 * 32 = 160 MHz, which is within
the 100-200 MHz ranged needed.
If PLLPOST<1:0> = 0, then N2 = 2. This provides a F
of 160/2 = 80 MHz. The resultant device operating
speed is 80/2 = 40 MIPS.

Oscillator Mode
OSC2 pin function is determined by the OSCIOFNC Configuration bit.
This is the default oscillator mode for an unprogrammed (erased) device.
