Hi,

Could you tell me about Lock and Unlock function?

”After entering diagnostic mode, each register is unlocked.
And Registers with WR SW LOCK PROTECT set to Yes can be locked.”

Is my understanding correct?
Please point out if my understanding is wrong.

Best Regards,
Yusuke

Hi Yusuke-san,

I confirm with systems and your understanding is correct. The recommendation is to lock registers (write SW_LOCK) when the device is in diagnostic state.
