How to obtain the lockstep status of the S32K342 chip core

Hello:
        I learned that the S32K342 chip is a lockstep chip, but my customers are obsessed with obtaining the lockstep status of this chip. Because they have functional security requirements, they must ensure that the lockstep function of the S32K342 chip is turned on, so I would like to ask how to obtain the lockstep status of this chip, the information stored in registers or flash memory.
                                                                                                                                          Best regret.

Hi@xinglong

Please take a look at the register:DCM_GPR “DCMROF19”

register bit 29 (bit LOCKSTEP_EN):

0 = decoupled mode

1 = lockstep mode
