DMA interrupt documentation error in RM0440

Pete4 · ‎2022-02-04

In RM0440, it states that "Generation of a single interrupt request for the DMA1 controller," however looking at the exception vectors indicates that there is a separate interrupt vector for each channel for both DMA 1 and 2. Also the stm32cube library header files reflect this.

Agreed. the NVIC interrupt vector Table 97 shows eight separate vectors for DMA1 and another eight separate vectors for DMA2.

ST needs to update the document.
