I want to create a DCF Miscellaneous record for an MPC5775E processor. As I understand it the DCF Miscellaneous record is a "Triple Voted" record. Does this mean in the OTP UTEST flash memory block I need to add three separate records (as highlighted in the example in the screenshot) into the OTP UTEST e.g 1st DCF record with normal Register Value, 2nd DCF record with an inverted register value, and the 3rd record with rotate right register value? OR do I just need to add a single DCF record with register values I want to set?
If I need to add 3 DCF records (as detailed above) what should If do if I get any of the register values wrong or want to use new values. Do I need to use the overwrite functionality and add another 3 DCF records after the previous 3 records? (i.e. how will the system know when a new set of 3 DCF records are needed in place of the previous one's set-up)
3 DCF records are needed only for devices marked below. MPC5775E is sub-derivative of MPC5777C device.
