6502 bit instruction

The 6502 also had a fairly regular instruction set. It had one accumulator A and two 8-bit addresses registers X and Y (so the latter could not hold 16-bit address like the 8080 and 6800). § Feeds the 6502 instructions. ?

The 6502 is an 8-bit microprocessor that was designed by Chuck Peddle and Bill Mensch for MOS Technology in 1975. A bit of background. I met some guys who considered this a bit weird: building a processor only using TTL ICs. But in the old days the processor was just 'another' part of the computer and was built from The 6502, in particular, holds a special place in many people's hearts. When it was introduced in 1975, the 6502 was, by a considerable margin, the least expensive microprocessor on the market. 6502 Instructions Most instructions that explicitly reference memory locations have bit patterns of the form aaabbbcc. The aaa and cc bits determine the opcode Classes of Instructions. Instructions Available on the 6502. A longer instruction will be represented by two or more bytes. Because the 6502 is an eight-bit microprocessor, it fetches bytes
