TMS320F2800156-Q1: DCSM CSM ALL_0 password

Part Number: TMS320F2800156-Q1

Hello,

I am implementing DCSM module and wish to permanently lock the device after a certain time (at runtime). I am using flash api library to program user OTP at runtime and successfully lock the device. The question I have is related to this snippet from user manual:
9bdfbcb6-17fc-46e8-8424-a3d93083cece.png

"Therefore, the user can never use ALL_0 password". Is this stated because the device will become permanently locked, or are there other side-effects of ALL_0 that are not stated? What if permanent lock is a desired outcome?


Best regards,

Matic
