9.5.2 Reads and Writes to SD/ MMC Using DMA Transfers
A DMA channel (out) is created to transfer data to the SD/ MMC device connected to any of the S-ports, and another DMA
channel (in) is created to read data from the SD/MMC device. Refer to FX3 DMA Subsystem chapter on page 58 for more
details on the DMA channels and sockets. Any of the six available S-port sockets can be used for these channels. The socket
is defined as follows inside the FX3 SDK library:
CY_U3P_SIB_SOCKET_0 = 0x0200, /**< S-port socket number 0. */
CY_U3P_SIB_SOCKET_1, /**< S-port socket number 1. */
CY_U3P_SIB_SOCKET_2, /**< S-port socket number 2. */
CY_U3P_SIB_SOCKET_3, /**< S-port socket number 3. */
CY_U3P_SIB_SOCKET_4, /**< S-port socket number 4. */
CY_U3P_SIB_SOCKET_5, /**< S-port socket number 5. */
