6502 CPU Tutorial

The 6502 CPU has a 16 bit address bus and an 8 bit data bus. It is powered by a 5 volt supply.

Interrupt requests tell the CPU to stop processing its present program and jump to another.

The reset pin is taken low to initialize the CPU when it is first powered on.

The read/write pin is taken low when writing to memory, and high when reading from it.

The 6502 has eight addressing modes telling the CPU  where data is located.
