TMS320F2800157-Q1: Question about CPU22 in functional safety manual

Tool/software:

Hi Champs,

In our TMS320F280015x Functional Safety Manual, regarding the security mechanism CPU22, in SDL, there is a corresponding software diagnosis code, which is a software security mechanism. However, in the table of security mechanisms, CPU22 is a hardware security mechanism. Customer think this is a bit contradictory, please help check it out. Thank you~
