Time to start / stop the RTC?

[CurtisHx]

What's the delay from setting the Start / Stop task in an RTC module to when the RTC actually starts or stops? Is it less than 1 clock cycle on the CPU (15ns)? More than one clock cycle?

[Susheel Nuguru]

If the LFCLK is already running and RTC is already configured, then it will be just one clock cycle to start by TASKS_START or to stop it by by TASKS_STOP.

Hence the lack of "EVENTS_STARTED" and "EVENTS_STOPPED" for the RTC... that should have been a clue to me there...
