EQUATION 7-2:
For example, suppose a 10 MHz crystal is being used
with the selected oscillator mode of XT with PLL.
• If PLLPRE<4:0> = 0, then N1 = 2. This yields a
• If PLLDIV<8:0> = 0x1E, then

VCO input of 10/2 = 5 MHz, which is within the
acceptable range of 0.8-8 MHz.
M = 32. This yields a 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.
