Software - 65816

This page includes software snips that are relevant only to the 65816 — that is, code which is either ridiculously hard to do on the 6502, or outright not possible at all. If you're looking for 16-bit code that is otherwise structurally identical to the equivalent 6502 code, you'll be better served on the software page instead.

• m and x flag independence
• Memory move
• Relocatable code using BRL and PER
• Speed considerations
• using the stack to pass and manipulate parameters
• Use MVN to fill a block of memory
