I'm trying to establish a time sync between a single master and multiple slaves. I found the "Time Sync Application Note" DOC00001686 which looks very helpful. The note mentions a margin of error of 61us which is limited by 2 ticks of a 32k RTC.
Has anyone tested whether this is the true limitation in practice or is it more of a theoretical lower bound on the error? (Are time sync errors in real implementations usually driven by other factors?)
(Newbie here, so please forgive if this is a very basic or redundant question.)
