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