TMS320F280049: DCSM RAM protection

Emma Wang

hi expert,

here is a description in 3.12.1 Functional Description
RAM: All LSx RAMs can be secure RAM on this device. These RAMs can be allocated to either zone by
configuring the respective GRABRAM location in the Bank0 USER OTP
but I found in the 3.13.6.14 Z1_GRABRAMR Register
there is only LS RAM4-RAM7

does it a mistake or we have another register to configure LS RAM1-RAM3.

Emma,

I downloaded the TRM for F280049 device and I don't see any issue. Also the Z1_GRABRAMR register section is not what you mentioned in the TRM. It's section 3.14.6.14 so please check if you are looking at right document.

Ok, on that device we only have LS4..LS7 so GRABRAM description is correct.
