Hi ,
I have to measure/verify different pheripheral clock frequency like eQADC,DSPI,PIT,eTPU ,M_CAN etc of MCP5777c microcontroller .I am using evalution board of MCP5777c and IDE S32DEv1.2 .So please suggest me any solution to measure all these pheripheral clock frequency.
Hi,
On MPC5777C are implemented CMUs (clock monitor unit) for clock frequency violation measurement.
Please refer to reference manual Chapter 22 Clock Monitor Unit (CMU) for details on how to use them.

Thanks for your valuable reply ,I have studied CMU module but I want to measure all pheripheral frequency using DSO(Digital storage Ocsilloscope)so,is there given any test point on EVB of MCP5777c ?
Hi,
There is CLKout for clock source frequency measurement.
Rest you have to calculate from desired dividers in AUX modules.
