AM263PX-RESTRICTED-SECURITY: MPU Firewall

Part Number: AM263PX-RESTRICTED-SECURITY
Other Parts Discussed in Thread: SYSCONFIG

Hi Team,

In the SysConfig of the HSM firmware for the MPU, I restricted access to DTHE_SLV for the R5FSS0_0 core. However, I am still able to perform DTHE_open(), AES encryption, and other cryptographic operations without any errors.

I expected that restricting R5FSS0_0 from accessing DTHE_SLV would result in an access violation or an error, but that did not happen.

Can I know the reason why these operations are still working despite the access restriction?
