Hi,
Is it better to use push/pop to save/restore SREG or a general pourpose register ?

What is different about the two
Thanks

 

Both.
I always push then pop on chips with the stack in RAM. That's why the stack is there. On chips with hardware stacks, stack space is too precious so I use a dedicated memory location or a dedicated register.

 

Thankyou Mr.DickCappels .A few hours ago I read that there is a slight difference regarding the speed ( n° cycles),
but in my application It's irrelevant
