Thank you for the quick response.
Sadly this ADC is really slow (3.3ksps) therefore we still have to switch to an external ADC, but this explains the differences.
I also just saw that the chart shows 3xPWM but the list mentioned above says 6x (and they are also not implemented on M4, only A53). Could this be because the other three are already in use (for Display, UART, etc)?
