TMS320F280048-Q1: How to confirm the ZONE is unlocked by the PMF.

Part Number: TMS320F280048-Q1

Hi Experts,

Could you please let me clarify how I can confirm the ZONE is unlocked after the CSM Password Match Flow (PMF) is done?

1) I believe that DcsmBank0Z1Regs.Z1_CR.bit.UNSECURE and DcsmBank0Z2Regs.Z2_CR.bit.UNSECURE reflect the ZONE is unlocked. Am I correct?
2) If so, are there any timing delay until the UNSECURE bit is set just after the PMF is finished?

Thank you for your kind check.
Best regards,
Hitoshi
