eSCI and DMA on MPC5777C

[berat24]

Hello everyone,

When I looked at the RM to understand eSCI hardware and its relationship with DMA, I perceived that I should set TXDMA bit in CR2 register after configuring eSCI and DMA. However, I could not recognize when DMA will transfer data from system memory to SDR register. 

Could you inform me about that?

Sincerely.
