XBAR SETTINGS FOR DMA on MPC5777C

[berat24]

Hello everyone;

I will send commands from RAM to eQADC FIFOs with eDMA. As far as I know, I have to set eDMA priority higher than other master ports for SRAM on XBAR. For this purpose, I did settings below.

XBAR->PORT[2].CRS = 0x00100004;
XBAR->PORT[2].PRS = 0x76504321;
XBAR->PORT[4].PRS = 0x76504321;
XBAR->PORT[4].CRS = 0x00100004; 

These are correct and enough to set eDMA for the highest priority?

Hi, you should also set it for AIPS_1 and AIPS_0.
