time is a 64 bit value indicating the time in usec since power-on<br />
|
|||
|
|
timeh is the top 32 bits of time & timel is the bottom 32 bits<br />
|
|||
|
|
to change time write to timelw before timehw<br />
|
|||
|
|
to read time read from timelr before timehr<br />
|
|||
|
|
An alarm is set by setting alarm_enable and writing to the corresponding alarm register<br />
|
|||
|
|
When an alarm is pending, the corresponding alarm_running signal will be high<br />
|
|||
|
|
An alarm can be cancelled before it has finished by clearing the alarm_enable<br />
|
|||
|
|
When an alarm fires, the corresponding alarm_irq is set and alarm_running is cleared<br />
|
|||
|
|
To clear the interrupt write a 1 to the corresponding alarm_irq</div></li><li><div class="item-name"><a class="struct" href="struct.TimerBackend.html" title="struct rtic_monotonics::rp2040::TimerBackend">Timer<wbr>Backend</a></div><div class="desc docblock-short">Timer implementing <a href="../trait.TimerQueueBackend.html" title="trait rtic_monotonics::TimerQueueBackend"><code>TimerQueueBackend</code></a>.</div></li></ul></section></div></main></body></html>
