When the RTC in is any of the Interrupt modes can the time date/time of day be read.
thanks
You can read the date/time if you activated any of the time or periodic interrupts on the RTC. But you probably should not do so inside an interrupt handler as they should be short and fast.
I have the RTC connected to an Arduino (qwiic connector and RTC’s INT pin). I setup the RTC to interrupt once a minute. I put the Arduino to sleep and the RTC’s interrupt (or one from another source) will wake the arduino up. My interrupt handler on the arduino is empty, but the main loop checks to see if there was and interrupt from the RTC and and if so, fetches the time.
