Hello ST Community,I am using RTC backup register of STM32F746ZG for saving some accumulating data.So i'm afraid of situation when i start write operation and in the same time the VDD power is disabled.Couldn't find any information about this, so i a...

Hello, i am using STM32F746ZG to sample and process large amounts of ADC data. To increase it's speed dual interleaved mode is used. And because of low processing speed, the main idea is sample many samples of single channel (~50K) and process them. ...

Thanks for you answer!I can deal with updating only half (actually I'm using only one register for that kind of data).

Ok, I think, i found needed information. According to RM0385, when using multi-mode ADC with DMA (not circle buffer -> you need to trigger ADC by software):If the conversion sequence is interrupted (for instance when DMA end of transfer occurs), the ...

Can the contents of RTC backup register become corrupted in case of VDD power reset while write operation is ongoing (VBAT is present)?

ADC in dual interleaved mode with normal DMA buffer.
