Hi,

I'm using SDCC with an AT89C52 and I just want someone to double check my code and data locations.

According to the memory org charts amtel provides, http://www.atmel.com/atmel/acrobat/doc0498.pdf,
I guess my settings should be
sdcc --model-small --data-doc 0x30 --code-loc 0x00 --stack-after-data

but what about the --xram-loc? This is 8K of flash, which means its read only, or should i set it to 0xFF and just make sure I access everything indirectly to get to the extra 128 bytes of RAM?

Regards
Chris Pope
