Implements all WDC 65C02 instructions and is cycle-accurate
a synthesizable 8-bit MOS 6502 processor in VHDL fully synthesizable on the IR stores the opcode through the instruction execution cycle starting from ...
The Operation Code (OpCode) portion of the instruction is loaded into the Instruction Register from the Data Bus and is latched during the OpCode fetch cycle.
