The initial countdown value and present countdown values should match immediately after the countdown is initialized via a Set Watchdog Timer command and after a Reset Watchdog Timer has been executed. Note that internal delays in the BMC may require software to delay up to 100 ms before seeing the countdown value change and be reflected in the Get Watchdog Timer command. |
| 9 | Present countdown value, msbyte |
