QorIQ LS1046A DMAMUX no always-enabled/on slot DMA source config information in the reference manual

Hi,

LS1046A DMAMUX

Issue : Use of always-enabled/on slot DMA source.(like for memory to memory transfer)

The following sections in the datasheet is not providing what values to set for always-on or always enabled DMA source?
1. Section 16.4.1.2 Channel Configuration register (CHCFG0 - CHCFG15)
2. Section 16.5.3 Always-enabled DMA sources.

The datasheet talks about to configure the always enabled source, but where and what needs to be configured is not detailed. 

Is there any other DMAMUX module for this chip that needs to be checked for this? Please let me know.

I am currently implementing code for memory to memory transfer.

If you want to configure a channel as always-on, you should set CHCFGx[SOURCE] = 63 All other steps specified in LS1046ARM, Section 16.6.2 do apply.

Hope this helps,
