Setting RTC binary mixed mode on STM32WLE leads to normal operation of BCD Alarm and wake-up counter plus their wakeup and IRQ triggering-so far so good. It behaves similar when set to binary mode only - binary alarm etc work as expected. So what is the difference between RTC's BCD mode and mixed mode? In mixed mode I would expect, that both binary and BCD (calendar) alarms work in parallel, but I do not get the binary alarm IRQ. IMHO there is no apparent difference between RTC calendar and binary mixed modes. Any explanations/thoughts on this somebody?
