so i want to use specific places in the SRAM of my arduino (AVR) using assembly . for example i want to use all the ram addresses from a to b for an array of mine in assembly . the thing is how can i know if that address is used by the C program . i am using inline assembly with the usual arduino language . so how can i know if the space i am addressing is used or not .
i dont want to use directives like .byte or stuff like that . i just want to use number addresses
