TMS320F28377D: Secure and unsecure boot ROM

Part Number: TMS320F28377D

Dear TI hello,

In chapter 4 in TRM, we have in Table4.1 two types of Rom, secure and unsecured,

I don't know why we have two types, is this related to Zone 1 and Zone 2 in the Z1_BOOTCTRL register?

What is the purpose of this ROM secure section?

Thank you in advance for your help,

S.T

    Hello S.T.

    The Secure ROM is used by certain users to protect their data during run time from unauthorized reads and modifications even if using a TI debugger. The two zones allow the user to specific the permissions (ex: Execute only, Read , Write Execute, etc.) based on the application.
