Clarification on eMIOS DMA Request Mapping

Hello Team,

I am currently using eMIOS1_CH13 for the LiPS sensor in DMA mode. The configuration uses DMA Channel 0 and DMAMUX0.

While reviewing the S32K3xx DMAMUX mapping Excel, I observed that for eMIOS1, only DMA requests 0, 1, 9, and 10 are listed under DMAMUX0. However, my application is configured to use eMIOS1_CH13.

Could you please clarify the following:

Which DMA request source should be used for eMIOS1_CH13?
Does eMIOS1_CH13 support DMA triggering, or is DMA support limited to the eMIOS channels corresponding to DMA requests 0, 1, 9, and 10?
Thank you for your support.

Best regards,

Jyothsna Sagili
