5.5.5.5
The real time counter event register (RTEVR), shown in
interrupts. The register can be read at any time.
RTEVR bits are cleared by writing ones. Writing zeros does not affect the value of the status bits.
Table 5-44
5.5.5.6
The real time counter alarm register (RTALR), shown in
value. When the value of the RTC counter equals the RTALR[ALRM] value, a maskable interrupt is
generated.

Write reserved, read = 0
Alarm interrupt flag bit.
Used to indicate the alarm interrupt. It is set if the RTC issues an interrupt after the RTC counter counts to
zero.
Second interrupt flag bit.
Used to indicate the every-second interrupt. This status bit is set each time that the prescaler count reaches
zero and should be cleared by software.
The alarm interrupt is generated when the value of the RTC counter equals RTALR[ALRM].
