* \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(). | |
