Hi,

In assembler, how can we initialize the register to 0000? Are there some best practices to choose from? Appreicate your help.

Code: Select all

         SR    <your-reg>,<your-reg>
         ...
         XR    <your-reg>,<your-reg>

once upon a time
( when people looked at the smallest details to squeeze everything out of the CPU available )
XR was preferred for being slightly faster

nowadays the issue is probably irrelevant
