Sequencer clock source and frequency?

[SWenn.1]

I am using an STM32WLE5 board and running the following github code:

https://github.com/danak6jq/Seeed-LoRa-E5 

I have been searching all morning and cannot seem to find what the clock source (to be exact what file and line of code) is to the sequencer.  I am assuming it is like any piece of hardware and should have registers to configure it.  I would like to know what the frequency with which it wakes up at and what it's clock source is??  At this point I tend to believe it is the RTC as I cannot find anything in systemclock files that indicate SYSCLK is being used.

can someone point me to where this info is?  The IRQ handler for SysTick is empty and the RTC looks like it is set for AlarmA (from CubeMX) but RTC Handler seems to call AlarmA calback which is still defined as weak?

Appreciate any insight here....

ps....added a cubemx pdf print out of settings if that helps.

Thanks

Hello @SWenn.1 

First, let me clarify something. The Sequencer is a Software Solution designed as a simple alternative to using a real-time operating system for less complex application cases. All you want to know about this Utility is well explained in this WIKI.

Best Regards.
