S32K116 UART DMA example?

Is there available example for LPUART usage with DMA on S32K116 mcu?


The reference manual does not provide any proper documentation about how to set for example TX UART DMA...

For example where can I check the chip-specific DMAMUX information for details about the peripherals and their slot numbers?


the figure 19-2 is quite interesting but says nothing about how to map TX UART trigger to the proper dma channel... and in overall the complete dma concept is quite confiusing for me... is there an application note for S32K to how to use DMA with preiodic trigger mode on UART TX ?
