RTC registers
Refer to
RTC control register high (RTC_CRH)
Address offset: 0x00
Reset value: 0x0000
These bits are used to mask interrupt requests. Note that at reset all interrupts are disabled,
so it is possible to write to the RTC registers to ensure that no interrupt requests are pending
after initialization. It is not possible to write to the RTC_CRH register when the peripheral is
completing a previous write operation (flagged by RTOFF=0, see
390).
The RTC functions are controlled by this control register. Some bits must be written using a
specific configuration procedure (see
Bit 2 OWIE: Overflow interrupt enable
Bit 1 ALRIE: Alarm interrupt enable
Bit 0 SECIE: Second interrupt enable
