The 6502 instruction set contains 52 different instruc- tions, and at first sight may appear to be very similar to that for the 6800 series microprocessors Instructions
56 Instructions. Decimal and Binary Arithmetic. • Thirteen Addressing Modes. True Indexing Capability. • Programmable Stack Pointer. • Variable Length Stack.
Instructions in this group have fixed (f) and variable (v) bits as follows The size of this program is very small considering the complex task it.
