Vrefint and Vts very noisy with SAI active on G4

We are using an STM32G491 with TDM audio output active on SAI. When activating the 4 MHz bit-clock on SAI1_SCK_A, Vref and temperature measurement become very noisy, while externally connected ADC inputs are not affected.See attached graph for differ...

STM32H5 high-cycle data read more than 16bit at once

Hi,I'm using STM32H563 and managed to set FLASH_EDATA1R_CUR as needed (EDATA1_EN="1", EDATA1_STRT="111"). Then I tried to read 64-Bit at once from Address 0x09000000. Unfortunately I get a hard fault. Is it intended to read more than 16 bit from the ...
