20.3 RTC INTERRUPTS
w
The Real Time Clock (RTC) is associated with two Interrupt event flags.
The RTC_PER_EINT interrupt is set each time a periodic timeout occurs. The periodic timeout is
configured using the RTC_PINT_FREQ field described in Table 72.
The RTC_ALM_EINT interrupt is set when the RTC Alarm is triggered. The RTC Alarm time is
configured as described in Section 20.2.
Each of these secondary interrupts triggers a primary Real Time Clock Interrupt, RTC_INT (see
Section 23). This can be masked by setting the mask bit(s) as described in Table 71.

Table 71 Real Time Clock (RTC) Interrupts
The frequency of the RTC periodic interrupts is set by the RTC_PINT_FREQ field, as described in
Table 72.
