That chip family has a Flash and a One Time Programmable Area.

I have not used the programmer you have. I have programmed that family of MCU's only with my universal programmer with and adapter for specific package.

To export memory contents to a file, check section 7.4.5 of the CCS User's Guide.

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...
