Implementations

impl CPU

pub fn dasm(&self, address: u16) -> String

Disassembles code at (address)

impl CPU

pub fn new() -> CPU

Creates a new CPU instance and its 16 bits address bus.

pub fn execute(&mut self) -> u8

Fetches and executes one instruction from (pc). Returns the number of consumed clock cycles.
