DMAMUX Channel Configuration register SOURCE Values for S32K144

KARTHKSARODE — Tue, 15 Mar 2022 12:16:58 GMT

I was exploring the DMAMUX register description , I couldn't found any source list for DMA Channel Source (Slot)

I have gone through all the attached excel sheets , still I was not able to see slot numbers for peripherals

Where can I get those values ???

For example : FlexCAN0 source value is 54

Hi,

it is within S32K1xx DMA Interrupt Mapping.xlsx.
But this is unfortunately missing in the rev14 of the RM, if have previous version (rev13) please refer to it.

Hi @PetrS

I could download rev13 reference manual , I could able to see the source list of peripherals

but the corresponding equivalent integer number is missing

for example DMA TX Request has instance lpspi1 , but the equivalent number should be 17

but 17 is not visible anywhere (It is placed in row no.20)

Let me know , what I'm missing exactly??
