This is a Z80 emulator.

Example for a small loop:

```rust

use zilog_z80::cpu::CPU;

let mut c = CPU::new(0xFFFF);

c.reg.pc = 0x0100;                  // sets pc to 0x0100

// Here we create a small machine code program for demo purpose.

// Usually you will rather load an assembled code in memory with the load_bin function.

c.bus.write_byte(0x0100, 0x3e);     // LD A,0x0F

c.bus.write_byte(0x0101, 0x0F);

c.bus.write_byte(0x0102, 0x3d);     // DEC A

c.bus.write_byte(0x0103, 0xc2);     // JP NZ,0x0102

c.bus.write_word(0x0104, 0x0102);

c.bus.write_byte(0x0106, 0xc9);     // RET

loop {

    c.execute();

    if c.reg.pc == 0x0000 { break }

}

```
