- * and the value to 0.
- * \param rtc Base address of the RTC (i.e. &AVR32_RTC).
- * \param osc_type The oscillator you want to use. If you need a better
- * accuracy, use the 32 KHz oscillator (i.e. RTC_OSC_32KHZ).
- * \param psel The preselector value for the corresponding oscillator (4-bits).
- * To obtain this value, you can use this formula:
- * psel = log(Fosc/Frtc)/log(2)-1, where Fosc is the frequency of the
- * oscillator you are using (32 KHz or 115 KHz) and Frtc the frequency
- * desired.
- * \return 1 if the initialisation succeds otherwize it will return 0.
