| description: | |
| Startup time in microseconds. |
| |
| The value can be obtained by first measuring the time between |
| TASKS_HFCLKSTART and EVENTS_HFCLKSTARTED. Then multiply |
| the value by 2 to account for temperature and supply variations. |
| |
| Note that the startup time will be longer usual on the first |
| power-up and as such should not be used to determine |
| startup-time-us. |
