Hey guys, i have some weeks programming some things in C2000 Launchpadxl-f28027, but still don't understand the functions of these statements, and it would be great if someone c

ould tell me what they do in the program.

#ifdef _FLASH
memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (size_t)&RamfuncsLoadSize);
#endif

What does it means this sentence? ^^

and what makes this sentence in the program:

FLASH_setup(myFlash);

If someone could explain me this, or can tell me where i can read to get an explanation, it would be great.

Regards from Venezuela.

    This function copies time critical code and Flash setup code to RAM

    The above is to initialize flash control registers. This function MUST be executed out of RAM. Executing it out of OTP/Flash will yield unpredictable results.
