Does M0 / 1 RAM of TMS320F28388D support ACCESS PROTECTION?

Other Parts Discussed in Thread: TMS320F28388D

Dear Sir
In the data sheet of TMS320F28388D, in "Table 8-1. C28x Memory Map", Yes is entered in the "ACCESS PROTECTION" column for M0 / 1 RAM, but "3.12.1.1 Dedicated RAM (Dx RAM)" of TRM. Then, there are sentences that do not correspond.
Which is right?


Note that TRM's "Table 3-245. MEM_CFG_REGS Registers" did not have a protection bit for M0 / 1 RAM.

Is it an error in the table in the data sheet?

Best regards

    There is known issue with DxACCPROT register which has missing protection bits for M0/M1 registers. This has been already fixed and updated document will be released this month.
