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 />

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</p>
