Hello Chris ans Steve, I want to do some stack pointer manipulation at the start of each interrupt vector code. I am not sure whether inline assembly will allow me to do this. So I want to start interrupt execution in assembly code and then the control will jump to 'C' part of code. I think inline assembly doesn't allow to use r0 to r3 registers in the code for manipulation. Please clarify on the same.
