[Coco] 6809 Push/Pull

[Salvador Garcia]

 Adding to this thread...

Is the developer allowed to do some thing like:

PSHS    X

PULS    Y


What if I try something like this:

PSHS    X,Y

PULS    X


Like others, just curious. :-) Thanks, Salvador

 The order of registers in PSHS and PULS is a fixed property of the
processor.  PSHS X,Y and PSHS Y,X generate identical opcodes, so it makes
no difference which you use.
