Hello, and welcome to this A Real Time Clock (RTC) is a timing element dedicated for keeping time. It covers the main features of this peripheral, which is used to provide a very accurate time base. The RTC can generate alarms, wakeup events, and timestamps that can wake the microcontroller from Sleep, Stop, or Standby modes. That is - the RTC counts the clock pulses (say coming from With the divided RTC clock, the wakeup period can be from 122 microseconds to 32 seconds when the RTC clock frequency is 32. g. This code should run together with an RTOS(Zephyr). Therefore, we can use What you are missing are the wakeup counters (below wakeup clock in your screen). However, they do not seem to apply to the C0 family.
