Yes. Note that the endurance of the two memories are several of orders of
magnitude differed (millions for the data memory, much less for the program).

They're not. The 0x2100 is an agreement between the assembler and the
programmer. When the programmer sees 0x2100 addresses it sends program
data memory commands instead of program program memory commands.

If you wrote internal software to program them, they code is different IIRC.
