\section{Notes}
For the opcodes that load or store data at the assembly language level we could have the mnemonics
"store" and "load" and have the assembler pick the opcode based on the inclusion of the word "byte"
or "word" for two bytes. That would make the assembly easier to read but put a bit more work on the
assembler.
