Phase Locked Loop (IPLL) frequency multiplier with internal filter
— Reference divider
— optional divide by 2 of VCO frequency
— Configurable internal filter (no external pin)
— Optional frequency modulation for defined jitter and reduced emission
— Automatic frequency lock detector
— Interrupt request on entry or exit from locked condition
Off Mode
Default after reset, as PLLON bit is zero
Run Mode
PLLON bit is one, CGMIPLL registers must be configured for desired target frequency.
