I am using STM32F767, unfortunately I have a problem with the DR register area in the RTC. Exactly the problem is with the 10th and 17th bits of this register. Setting "1" means that I am not able to change these bits to "0". Only resetting the BDCR ...

As I wrote earlier, the DR value changes correctly by itself. The problem only affects the update and only 2 bits in the DR register. I don't know what is causing this and I don't understand the mechanism. I also don't know how to do it to set it up ...

Actual value DR = 0x22a624, For August 1, 2022, the value of tmpreg = 0x222801. as a result of writing data to the DR register, I got a value from that register 0x222c01. Function end status = success. When I return to the settings, e.g. on July 31, ...

I have not changed the name. I am not using SPL. I write libraries myself as needed. As it didn't work for me, I started searching the internet. I found out of it "some" library and it turns out that it behaves the same. I don't understand why these ...
