MSPM0L1306: Trigger DMA transfer to SPI TX from Timer Capture INT Event

Hi,

My customer wants to send SPI data using DMA as soon as Timer Capture event is detect (less than 1usec).
It is too late DMA channel is enabled by software inside Timer interrupt service routine. It takes ~4usec.
According to TRM, it seems it is possible to generate Event from Timer and trigger DMA channel.
And I found there are some parameters configurable in Sysconfig.

So I configure TIMER-CAPTURE module like below. I guess this configures Channel 1 compare down event generates Event to DMA.


Then I configure DMA module like below. I thought this configures TIMER - CAPTURE event triggers DMA.
But the waring says "no DMA channel is configuring subscriber event".


I could not find where should I configure to map the Event to specific DMA channel (in my case Channel 0).

Thanks and regards,
