I am using TMS320F2812.

I want to store some data in non-volatile memory.Can i use internal ROM for this purpose?

I searched for protocol for accesing this ROM,but i havent got it.

Please i need help regarding this. 

ROM is read only memory that is populated as part of the manufacturing process.  It cannot be changed after the fact.  You could, however, use Flash by using the flash programming API library.
