//! A cycle-stepped, dependency-free MME U880 emulator.
//!
//! # Example
//!
//! ```
//! use u880::{Cpu, pins};
//!
//! let mut cpu = Cpu::new();
//! let mut mem = [0u8; 1 << 16];
//! let mut bus = 0u64;
//!
//! for _ in 0..32 {
//!     bus = cpu.tick(bus);
//!     if bus & pins::MREQ != 0 {
//!         let addr = pins::addr(bus);
//!         if bus & pins::RD != 0 {
//!             bus = pins::set_data(bus, mem[addr as usize]);
//!         } else if bus & pins::WR != 0 {
//!             mem[addr as usize] = pins::data(bus);
//!         }
//!     }
//! }
