TMS320F280049C: GS0-GS3 RAM memory protection by password

Tool/software:

Hi, 

I wonder how can I password protect the GS0-GS3 RAM memory using the password?

I can see that Z1/2_GRABRAMR can be set to associate the LS0-LS7 memory to Zone1 or 2 for protection.

I also see that the upper parts of the register are reserved, as shown in the 3.15.12.14.Z1_GRABRAM in SPRUI33H RTM document.

I cannot see that the GS0-GS3 are protected in the same way. Are they by any chance covered by the reserved bits or in some other way?

Regards.

Vlad
