Dear all Member,
1.) RTC-SCU-CPU-SRAM Transfer Speed over Serial Interface
Above Picture was taken from Reference Manual. Unfortunately I can't find a hint in the Manual how fast I can
read the Register com my RTC Register into CPU perhaps internal memory to use the time mark.
2.) synchronisation with external 1hz signal
If I use the internal RTC with the 32.768 kHz high precision internal clock source. The time base was not 100%
accurate. Therefore I have a 1 Hz external Signal that I can use to synchronize the RTC. Here, too, I found nothing
suitable in the Manual.
How would you proceed?
Thanks for your help

Sorry *****RTFM******
The RTC module is a part of SCU from programmming model perepcetive and shares
register address space for configuration with other sub-modulesof SCU. RTC registers
are instantiated in hibernate domain are mirrored in SCU. The registers get updated in
both clock domains over serial interface running at 32kHz clock rate.

Please do not take into account the question has settled
Best regards
