Do you have some pictures of the board and connectors ?

KG7AMV:
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.
