Hello,
I want to check if there is an equivalent instruction of the MOVX at the C language.
I tried doing in-line assembly with no luck.
Any assistance is appreciated
"One of the most common good reasons is if you have hardware memory-mapped into the external data space."
Of course.
XBYTE is effectively just a "magic number" address - hence I prefer using _at_.
Using _at_ automatically informs the tools that there is something at the specified location; using "magic number" addresses - whether via XBYTE or a pointer - hides this from the tools, so they have no reason to know that the address is "reserved"!
