 * \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().
