| Flag | Description | Purpose | Zero Flag (jz) | Set to 1'b1 in case 0 = a - b otherwise 1'b0 |
The Zero flag indicates whether the result of an operation is zero. If the Zero flag is set and the subsequent instruction is a jump zero, then jump to the specified encoded address. |
|---|---|---|
| Carry Flag (jc) | Set to 1'b1 in case 255 < a + b otherwise 1'b0 |
The Carry flag indicates whether an overflow occurred during an addition operation. If the Carry flag is set and the subsequent instruction is a jump carry, then jump to the specified encoded address. |
