How to set the DMAMUX source on 5748G?

I am selecting DMAMUX_0 source on 5748G,  and I am looking up a 5744p demo. On 5744P reference manual. There is a table so if I want to configure DMAMUX_0 as LINFlex_0 tx, just write DMAMUX_0.CHCFG[0].B.SOURCE = 0x14;

However I cannot find such a table on 5748G reference manual. Where can I find the DMAMUX source number?

I guess I found it. It's in chapter 71 Direct Memory Access Multiplexer.

Hi,

If you wan to use DMA transfers for LIN then do not forget configure AIPS bridge to grant DMA access to LIN on peripheral bridge.
