(((uint32_t)(__DMA_INSTANCE__) == ((uint32_t)DMA1)) ? 0UL : 8UL)

Helper macro to convert DMA Instance DMAx into DMAMUX channel.

Note:

DMAMUX channel 0 to 7 are mapped to DMA1 stream 0 to 7. DMAMUX channel 8 to 15 are mapped to DMA2 stream 0 to 7.

Parameters:

__DMA_INSTANCE__

DMAx

Return values:

Channel_Offset

(LL_DMAMUX_CHANNEL_8 or 0).
