TMS320F280045: Restrict peripheral registers access

Part Number: TMS320F280045

Hi there.

I am interested in the following question: The software consists of two parts, one of which is security-relevant and the other is not security-relevant. The two software parts are located in separate FLASH / RAM areas and are largely independent of one another. Is there a way to block access to hardware registers, especially watchdog registers, for the non-safety-relevant software part?
