Thanks so much for the feedback with my first question!
I now have a simple question I guess that could be solved in no time:
1) I'm using SRAM (addresses $20 to $28) to store some data (9 bytes);
2) I'm storing these bytes using STS (sts $20,r2...);
3) I'm trying to retrive value from address $20;
* I can't retrieve that value at the $20 address, for I'm trying to use a variable (r24 to store the address in the SRAM from which to retrieve data in current cycle).
* I'm using lds with immediate address value - this works ok, but how to use variable?
