CSL_DMAChanDir CSL_MmcsdDmaConfig::chanDir

Channel direction - Rd/Wr

CSL_DMAInterruptState CSL_MmcsdDmaConfig::dmaInt

State of DMA interrupt

Referenced by MMC_setDmaChanConfig().

Bool CSL_MmcsdDmaConfig::pingPongEnable

Ping-pong mode configuration for DMA. This mode is applicable only to C5515 DSP. This parameter is available for C5505 CSL also. No need to set this parameter for C5505 DSP. CSL APIs ignore this parameter while configuring the DMA for C5505 DSP. pingPongEnable = 0; Disables DMA Ping-Pong mode pingPongEnable = 1; Enables DMA Ping-Pong mode
