AT91RM3400
The Tempo Service allows a single hardware system timer to support several software timers
running concurrently. This works as an object notifier.
There are two objects defined to control the Tempo Service: AT91S_CtlTempo and
AT91S_SvcTempo.
The application declares one instance of AT91S_CtlTempo associated with the hardware
system timer. Additionally, it controls a list of instances of AT91S_SvcTempo.
Each time the application requires another timer, it asks the AT91S_CtlTempo to create a
new instance of AT91S_SvcTempo, then the application initializes all the settings of
AT91S_SvcTempo.
