The definitions for those functions are in the IFI library file. Unless you're going to talk to another device using the SPI bus (the bus IFI uses to link the master with the user) there is no reason to call that function. As far configuring the registers, I'm not sure what all IFI does there, but you should be able to configure the registers you need with your own code.
