Hi:
I Use CMU_1 to monit the CHKR_CLK;
System clok Divider 0 is 1, so CHKR_CLK is 100MHz;
I set CMU_1 HFREF 440 LFREF 360, why the CMU_1 report FLL event?
Help me Plz。
Hi,
solution is to enable lockstep core. LOCKSTEP EN in DCF in UTEST is 1 by default, so this is OK. It just need to be enabled also in boot header:
Then it will work as expected.

Hi:
I Try to solve the issues by write MC_ME_CCTL2 register,it's working fine。why?
Hi,
yes, lock step core will increase the current consumption. The lock step core should be enabled via RCHW, enabling via CCTL2 is not expected use case.

tks for your reply。
According what you said,I solved the issues. Enable the lockstep core will increase the system load?
