Macros
#define	UDMA_GET_TRPD_TR15_SIZE(n)   (UDMA_ALIGN_SIZE(sizeof(CSL_UdmapTR15) + ((n) * (sizeof(CSL_UdmapTR15) + 4U))))
	UDMA TR15 packet descriptor memory size in bytes. This contains the CSL_UdmapCppi5TRPD + Padding to sizeof(CSL_UdmapTR15) + N* Type_15 TR (CSL_UdmapTR15) + N* TR response of 4 bytes. Since CSL_UdmapCppi5TRPD header is less than CSL_UdmapTR15, CSL_UdmapTR15 itself is used for size alignment. More...
#define	UDMA_GET_TRPD_TR3_SIZE(n)   (UDMA_ALIGN_SIZE(sizeof(CSL_UdmapTR3) + ((n) * (sizeof(CSL_UdmapTR3) + 4U))))
	UDMA TR3 packet descriptor memory size in bytes. This contains the CSL_UdmapCppi5TRPD + Padding to sizeof(CSL_UdmapTR3) + N* Type_3 TR (CSL_UdmapTR3) + N* TR response of 4 bytes. Since CSL_UdmapCppi5TRPD header is less than CSL_UdmapTR3, CSL_UdmapTR3 itself is used for size alignment. More...
#define	UDMA_TR1_OFFSET   (32U)
	Offset for TR1 type TR from TRPD start address. More...
#define	UDMA_TR3_OFFSET   (32U)
	Offset for TR3 type TR from TRPD start address. More...
UDMA TR type
Various UDMA TR type supported
