This is a Z80 emulator.
Example for a small loop:
use zilog_z80::{cpu::CPU, bus::Bus, bus::FlatBus};
let mut b = FlatBus::new(0xFFFF);
let mut c = CPU::new();
c.reg.pc = 0x0100; // sets pc to 0x0100
// Here we create a small machine code program for demo purpose.
b.write_byte(0x0100, 0x3e); // LD A,0x0F
b.write_byte(0x0101, 0x0F);
b.write_byte(0x0102, 0x3d); // DEC A
b.write_byte(0x0103, 0xc2); // JP NZ,0x0102
b.write_word(0x0104, 0x0102);
b.write_byte(0x0106, 0xc9); // RET
loop {
c.execute(&mut b);
if c.reg.pc == 0x0000 { break }
}
