Bits 15:0 RTC_ALR[15:0]: RTC alarm low
Bits 15:0 RTC_ALR[31:16]: RTC alarm high
RTC alarm register high (RTC_ALRH / RTC_ALRL)
When the programmable counter reaches the 32-bit value stored in the RTC_ALR register,
an alarm is triggered and the RTC_alarmIT interrupt request is generated. This register is
write-protected by the RTOFF bit in the RTC_CR register, and a write operation is allowed if
the RTOFF value is ‘1’.
RTC alarm register high (RTC_ALRH)
Address offset: 0x20
Write only (see
Reset value: 0xFFFF
RTC alarm register low (RTC_ALRL)
Address offset: 0x24
Write only (see
Reset value: 0xFFFF
