| * \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(). |
