Checking Core Configuration Mode on S32K344 Q172 EVB (Lockstep/Dual-Core)

Hello,

I'm currently working on a project using the S32K344 Q172 EVB and I need to determine whether the MCU is configured in lockstep mode or dual-core mode. Is there a way to read or verify the core configuration mode that the S32K344 is set to? Any pointers on the registers or methods to check this information

Hi @Shivaprasad_sp

To check the chip's operating mode (Lockstep or Decoupled) you can read bit 29 (LOCKSTEP_EN) of the DCM_GPR -> DCMROF19 register. This bit returns the operation mode as configured in the DCF record (UTEST_MISC[LOCKSTEP_EN]).
