The 96 MHz PLL requires a 4 MHz input and it produces a 96 MHz output. The 96 MHz PLL prescaler enables
source clocks of 4, 8, 12, 16, 20, 24, 40 or 48 MHz to provide the 4 MHz input.
The 4x PLL requires an input clock source between 4 and 12 MHz. When using INTOSC to provide the 4x PLL
input, the INTOSC postscaler must be set to either 8 MHz or 4 MHz. Selecting other INTOSC postscaler settings
will operate the PLL outside of the specification.
Selecting the Timer1 clock or postscaled internal clock will turn off the primary oscillator (unless required by the
reference clock of Section 3.4 “Reference Clock Output”) and PLL.
