The figure is missing: Also, the figure that was there in Rev. 6 referred to DMAMUX_RGCnCR but it should have been DMAMUX_RGxCR.

Various STM32 products have opamps that have a mux in front of it.Ex: STM32G4, STM32F3, STM32H7 series, etc.If I change the mux input setting using the control status register (OPAMPx_CSR::VP_SEL or VN_SEL), how long does it take for the mux to switc...

I use HSI16 as my clock base which goes through a PLL and then into the HRTIM.Let's say that I adjust HSI16 periodically (every ~10 milliseconds) to track an external high precision clock.Is enabling the DLL calibration (HRTIM_DLLCR:CALEN, CALTRE) en...

Figure 188, Page 853: The last waveform (HRTIM_REPxR = 2) should be: 1, 0, 2, 1, 0 and not 1, 0, 2, 0.Figure 254, Page 933: For the last two waveforms (ADCxPSC[4:0]=4 ADROM[1:0]=01 and ADCxPSC[4:0]=4 ADROM[1:0]=10), it seems like the waveforms as sho...

PA9 - Alternate functions has "OMP5_OUT," instead of "COMP5_OUT,"

@MC.4ASTRO any update on the date? I recently saw an ST press release.

There is one DMA request from the I2C RX and another DMA request from the I2C TX.These go into the DMAMUX and you can map any DMA channel to the DMA request. Look at Table 91 in RM0440 for the mapping between the DMA request and the DMAMUX input sele...

I'm not following why the APB2 prescaler being /2 would cause double writes?I just checked the Reference Manual and the Datasheet and didn't see any requirements for clock frequency relationship between different clocks.Looking forward to your answer...

Awesome data! Thank you for making time to share it and explain what you did and the issue.In my application, the opamp is going into the ADC. So, I can adjust the sampling time so that the glitch has settled out.In your application, I'm guessing you...

@Amel NASRI Thank you for the information. It answers my question.No worries about the time it took to get an answer. I figured that since it wasn't documented, you must have reached out to the design or verification team to see if anyone knew the i...
