Delete branch "rtc_doc"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
I guess this relates to the "All RTC register reads and writes are done from the processor clock domain clk_sys. All data are synchronised back and forth between the domains. Writing to the RTC will take 2 clk_rtc clock periods to arrive, additional to the clk_sys domain. This should be taken into account especially when the reference is slow (e.g. 1 Hz)." note in section 4.8.4 of the RP2040 datasheet?
