I'm not experienced with the assembler for avr's but i'm doing my best to translate some code from asm to win-avr C.
What does this do?
subi is a substract command and r24 should be decrement by lo8(-2)
What value gives lo8(-2)?
What does lo8 do? Isn't that the low 8 bit of an 16bit word like low()?
Please tell me what this line does, thanks
