A pointer to an unsigned 16-bit integer that receives the number of a conflicted pin, if any.
A conflict arises if the pin is already assigned to another module and cannot be used by the SPI module. To fix this, check which module uses the pin (call the DlnGetPinCfg()function), disconnect the pin from that module and call the
DlnSpiMasterEnable() function once again. If there is another conflicting pin, its number will be returned.
