TMS320F28388D: CSM Password Match Flow Question

Part Number: TMS320F28388D


Greetings,

                I am looking at spruii0e, section 6.7.2 CSM Password Match Flow.  The fifth box down has two exit points with no conditional.  For the 379, spruhm8i, Figure 3-23 has a conditional preceding that box.  Should the 388’s flow chart have a similar conditional?

Thank you,

Ed

    Hi Ed Sanders,

    While there is a difference In the flow chart between TMS320F28388D and TMS320F3837x, the way it is captured in the Figure 6-23 is misleading. The condition of "Are CSM PWL = All F's" is an Invalid condition on  TMS320F28388D and will put the Device into BLOCKED state. This is explained in section 6.2.1. 

    The Yes path from the box "Write the CSM password of that zone into CSMKEYx registers" should be removed. I'll highlight this and get this corrected in the next revision. Thanks for bringing this to our attention. 

    Thanks & Regards
