MPC5646C CSE Erase All Key time

Dear Sir,

 

I am developing software for MPC5646C CSE.
I can load Keys and can use Debug Authorization command to erase all keys.
But I found that it takes too much time to complete the erase Key process, around 710ms for CSE to complete Debug Authorization command.

Is it normal? Do we have any data/spec describing how much time needed to execute each CSE command?

 

Regards,

Jason Yang
