Need Help for configuring the GPDMA for both SD/MMC and SPI for ADC Read

Hi All,

We are developing an application in which we are using SD Card Interfaced using MCI and DMA and
SSP0 is confiugred as SPI with DMA to read the data from the ADC to USB RAM.

But i have some confusions with the implementation sucha as

1. Can i use the Channel 0 for MCI when required for SDMMC and same channel 0 for the reading of ADC when required to send the Command.

2.As of I feel we should not configure the interrupt for the SPI for recieving, when we receive the data to the SPI RX buffer the data will be moved to the memory through the GPDMA. Is Wat i am thinking is correct
