Closed Turro75 closed 3 years ago
according to what did in CMP, I tested this case and it fails:
it('should execute a subs r5, r3, r2 instruction', async () => { await cpu.setPC(0x20000000); await cpu.writeUint16(0x20000000, opcodeSUBSreg(r5, r3, r2)); await cpu.setRegisters({ r3: 0 }); await cpu.setRegisters({ r2: 0x80000000 }); await cpu.singleStep(); const registers = await cpu.readRegisters(); expect(registers.r5).toEqual(0x80000000); expect(registers.N).toEqual(true); expect(registers.Z).toEqual(false); expect(registers.C).toEqual(false); expect(registers.V).toEqual(true); });
subs r5, r3, r2
I'm sending a new PR to (hopefully) definitely close this bug
Great, thank you!
