| 24 | Reverse the blink logic. If set to 0 (default) blink on for | |
| 25 | delay_on ms, then blink off for delay_off ms, leaving the LED | |
| 26 | normally off. If set to 1, blink off for delay_off ms, then | |
| 27 | blink on for delay_on ms, leaving the LED normally on. | |
| 28 | Setting this value also immediately changes the LED state. | |
