Hi All,

 

I am using MK70FN1M0VMJ15, I could set the CLK to 150Mhz and 12Mhz using _lpm_set_clock_configuration() but when I set to 2Mhz system got hang (not responding), code flow went to Cpu_SetClockConfiguration() ->  Cpu_SetMCG(1U); 

in Cpu_SetMCG() 1st it executed Cpu_SetMCGModePBE then it executed the Cpu_SetMCGModeFBE() immediately it got hanged in there. i am not sure what happens. Can anyone help me to fix this issue.

 

Thanks in advance.
