All internal registers retain data at 0 Hz.
Up to the maximum frequency rating of the device (see
“Loss of Reference Frequency” is the reference frequency detected internally, which transitions the PLL into self clocked mode.
Self clocked mode (SCM) frequency is the frequency that the PLL operates at when the reference frequency falls below f
This frequency is measured on the CLKOUT pin with the divider set to divide-by-2 of the system clock. NOTE: In SCM, the
MFD and PREDIV have no effect and the RFD is bypassed.
This parameter is meant for those who do not use quartz crystals or resonators, but CAN osc, in crystal mode. In that case,

This specification applies to the period required for the PLL to relock after changing the MFD frequency control bits in the
synthesizer control register (SYNCR). From power up with crystal oscillator reference, the lock time will also include the crystal
startup time.
PLL is operating in 1:1 PLL mode.
VDDE = 3.0 to 3.6V
Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise
injected into the PLL circuitry via V
for a given interval. CLKOUT divider set to divide-by-2.
Values are with frequency modulation disabled. If frequency modulation is enabled, jitter is the sum of jitter + Cmod.
Modulation depth selected must not result in f
f
Note that the ICO frequency may be higher than the maximum allowable system frequency, in that case, the FMPLL
Synthesizer Control Register Reduced Frequency Divider (FMPLL_SYNCR[RFD]) must be set to divide by 2 (RFD=0b001). In
other words, for a 40 MHz maximum device (system frequency), the FMPLL should be programmed to generate 80 MHz at the
ICO output and then divided by 2 by the RFD to provide the 40 MHz system clock.
