The C6502 is a fast 8-bit microprocessor IP core that implements the same instruction set as the 65C02 microprocessor, which is an upgraded version
of the popular NMOS-based MOS Technology 6502 8-bit CPU. The C65C02 provides software and hardware interrupts for interfacing external devices.
With sixteen addressing modes, including indirect index and zero page, the C6502 is able to address up to 64KB of external memory with two byte long
instructions. The 8-bit arithmetic-logic unit can operate on signed and unsigned binary numbers as well as binary-coded decimal numbers. The C65C02 core offers two instructions for efficient power management: STP for halt processor and WAI for wait for interrupt instruction.
