| 1 | A1 | 0 | s | The comparison result is output here. |
| 2 | A2 neg | 0 | s | The negated comparison result is output here. A 1-bit value is output. |
| 3 | A3 (sbc) | 0 | sbc | The comparison result is output here. A 1-bit value is output. |
| 4 | A3 neg (sbc) | 0 | sbc | The negated comparison result is output here. A 1-bit value is output. The output does not send during a restart. |
s = send, sbc = send by change
