23.2.9 RTC Interrupt Enable Register

The real-time clock interrupt enable register (RTCIENR) is used to enable/disable the various real-time
clock interrupts except the 2HZ bit (RTCIENR[7]). When an event of the types included in this register
occurs, if that bit in this register is set, then the corresponding bit will be set in the RTC Interrupt Status
Register (RTCISR). For more information about the frequency of the sampling timer interrupts
(SAM7-SAM0), refer to Table 23-1.
