Literals in assembler
Web5 mei 2024 · The asm string literal you pass in is actually evaluated at compile time and not at run-time. Thus the only valid argument for asm() is a string, not anything that requires memory access. Since the AVR architecture is a modified Harvard architecture, program memory and data memory are separate. Web23 jun. 2024 · The operand is one or two bytes in size so every machine instruction is either one, two, or three bytes in size. The 6502 is little endian so any addresses in the program get encoded LSB first and MSB second. If an operation has an operand of the address $1234 then the assembler will encode that address as $3412.
