1. Configuring a DMA channel to select source 0 or any of the reserved sources disables that DMA channel.
2. The several FlexCAN DMA Rx will be OR'd with the DAC.
11.1.1.2 DMA trigger sources
The DMAMUX on this device also supports a periodic trigger mode. The trigger sources
are from TRGMUX output showed in following table. The triggers from TRGMUX
module can trigger a DMA transfer on the first four DMA channels (channel 0 -3), for
example, the LPIT can trigger DMA via TRGMUX.
