By default, if an array of several frames is transmitted between the master and the same slave, the SS line stays enabled until data transmission completes.
However, some SPI slave devices require the SS line to be deasserted between frames.
To release the SS line, use the DlnSpiMasterReleaseSS(). Use the DlnSpiMasterSSEnable() function to enable the SS line.
If an SPI slave device is not fast enough to process continuously incoming data, you can configure your DLN adapter to introduce a specified delay between frames. For more information about this and other delays, read SPI Delays.
