Line 8: ==Features of the W65C02S== 8-bit data bus 8-bit ALU, Accumulator, Stack Pointer, Index Registers, Processor Status Register 16-bit Program Counter 69 instructions 16 addressing modes 212 Operation Codes (OpCodes) Wide operating voltage range (Specified at 1.8, 2.5, 3.0, 3.3, 5.0 v +/- 5%) Low Power consumption, 150uA @ 1 MHz 16-bit address bus provides access to 65,536 bytes of memory space Vector Pull (VPB) output indicates when interrupt vectors are being addressed WAit-for-Interrupt (WAI) and SToP (STP) instructions reduce power consumption, decrease interrupt latency and enable synchronization with external events Variable length instruction set enables smaller code optimization over fixed length instruction set processors. This results in low power as well *Fully static circuitry allows stopping the clock to conserve power ==W65C02S Datasheet==
