https://devzone.nordicsemi.com/f/nordic-q-a/14459/clock-monitoring-functionDear nordic. I am testing with nRF51822, and have some question about hardware stability check. nRF51822 have Clock Monitor Unit (Clock fault detector)? Is WDT same to Clock Monitor Unit? I can&#39;t find CMU in pdf file. nRF51822 Producten-USTelligent Community 13Thu, 16 Jun 2016 11:47:47 GMThttps://devzone.nordicsemi.com/thread/55230?ContentTypeID=1Thu, 16 Jun 2016 11:47:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f364823e-f11a-453f-90a4-b63b0b00728aOle Bauck<p>There is no such module on nRF51.
