* \par Purpose
*
* Interface for Real Time Timer (RTT) controller.
*
* \par Usage
*
* -# Changes the prescaler value of the given RTT and restarts it
* using \ref RTT_SetPrescaler().
* -# Get current value of the RTT using \ref RTT_GetTime().
* -# Enables the specified RTT interrupt using \ref RTT_EnableIT().
* -# Get the status register value of the given RTT using \ref RTT_GetStatus().
* -# Configures the RTT to generate an alarm at the given time
* using \ref RTT_SetAlarm().
