Simulation of loss of lock

Hello community,

 

In MPC5744P there are FCCU faults (NCF[24] and NCF[25]) defined for detection of loss of lock. These 2 faults are not injectable. The LOLF bit of PLLDIG_PLL0SR register is w1c. Is there any possibility that the faults can be simulated? Thank you.

 

For configuration I have done this:

PLLDIG.PLL0CR.B.LOLIE = 1

PLLDIG.PLL1CR.B.LOLIE = 1
