EQUATION 8-2:
For example, suppose a 10 MHz crystal is being used,
with “XT with PLL” being the selected oscillator mode.
• If PLLPRE<4:0> = 0, then N1 = 2. This yields a
• If PLLDIV<8:0> = 0x1E, then M = 32. This yields a
• If PLLPOST<1:0> = 0, then N2 = 2. This provides

VCO input of 10/2 = 5 MHz, which is within the
acceptable range of 0.8-8 MHz.
VCO output of 5 x 32 = 160 MHz, which is within
the 100-200 MHz ranged needed.

OSC2 pin function is determined by the OSCIOFNC Configuration bit.
This is the default oscillator mode for an unprogrammed (erased) device.
Note 1: This frequency range must be satisfied at all times.
