With the limitations, the 6502 instruction set allows for multiple addressing options to reduce the number of processor cycles and speed up the program. The 6502 has two addressing modes, immediate and indirect. The immediate mode is used when the instruction is followed by a value that is used as an address. The indirect mode is used when the instruction is followed by a value that is used as an address, but the value is not used directly as an address, but instead, the address of the value is used.
