WebAll timers require a clock of some sort. Most will be connected to the microcontroller’s main CPU clock (others, like real time clocks, have their own clock sources). A timer will tick (increment by one) each time it receives a clock pulse. In this demo, we will be using an STM32 Nucleo-L476RG, which has a default main clock (HCLK) of 80 MHz.

Websources: the RTC clock (RTCCLK) is used for the RTC timer counter, and the APB clock is used for RTC register read and write accesses.
