TMS570LC4357: PCR Access Management: Safety Features P1T2, P2T2 and P3T2

Hello,

The "Safety Manual for TMS570LC4x Hercules ARM Safety MCUs" (SPNU540A) specifies safety features P1T2, P2T2 and P3T2, "PCR Access Management: Protection Mode and MasterID Filtering".
Section 7.92 of the Safety Manual states that "These safety mechanisms are disabled after reset. Software must configure and enable these mechanisms."

Could you explain how P1T2, P2T2 and P3T2 can be configured and enabled?


Thank you.
