single DMA buffer for two timers STM32G0xx

[Akoli.2]

Hello. In a project with stm32g030 (071) I use two different timers to generate two PWM signals. The triggering of timers and PWM signals is out of phase by 180 degrees. Can I use one DMA buffer to load data into CCMR registers of two different timers?

Yes, why not.

DMA is just a simple busmaster which upon some stimulus reads memory and writes to peripheral. It does not care at all, whether any other busmaster or other channel of the same DMA reads the same memory.

Thank you. I don't see any problems either. Due to the phase shift, the timing of DMA channels accessing the buffer is different. But I decided to consult to be sure.
