STM32H7 ADC 8-bit dual mode with DAMDF=0b11 is ambiguous in reference manual RM0433

on page 997 of RM0433 Rev 7 it first says 2 bytes are transferred each DMA request, and then that 4 bytes are transferred each DMA request:DAMDF=0b11: This mode is similar to the DAMDF=0b10. The only differences are thaton each DMA request (two data ...

STM32H742 rev V ADC BOOST bits

Hello,I use STM32H742 rev V. In contrast to rev Y register ADCx->CR has two bits BOOST. I set both, because I want the highest ADC speed. But reading ADCx->CR back, with the debugger or in the running program reports only BOOST 0 set. What is wrong t...
