How to use inline ASM using WinAVR
I have been working on the optimization of one of my C codes. I needed one function to be as optimal as possible. I decided to use inline ASM to achieve this. I decided to write a few lines about this. There are a few rules that are necessary to follow. Each ASM statement is divided by colons into 3(up to four parts): Assembler instructions part; A list of output operands (comma separated); A list of input operands (comma separated); Clobbered register – usually left empty.
