placing data into program memory - Alexandre Freire da Silva Osorio - Oct 16 17:47:00 2002

Hi,

I'd like to know what's the correct procedure to place data into program memory
in C6202. If I symply place my vector variable using DATA_SECTION pragma, the
values read from this vector are wrong. Is there any bit to set in some internal
control register?

Thank you
Regards,
Alexandre

with LDW/STW instructions.
The only way you can access it is with DMA.
