DMA requests are still generated if the CCR is outside the auto-reload range

The DMA request is is generated when CNT reaches 0 rather than being disabled.

Processor is a STM32H750

is this a bug or a feature - it should be documented anyway

This is a known, documented, albeit admittedly surprising behaviour (it has been discussed on this forum several times).

Note, that DMA requests are consequence of the event which sets the CCxIF flag.

Many thanks +++. It could still be better documented in the next revision of the manual please.
