EQUATION 8-2:
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

Oscillator Mode
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.
