Function Prototype : void ConfigIntSPI1(unsigned int config)
 
Include            : spi.h
 
Description        : This function configures the SPI Interrupt
 
Arguments          : config - SPI interrupt priority and enable/disable 
                     information as defined below
					 Interrupt enable/disable					
					    SPI_INT_EN					
					    SPI_INT_DIS					
					 Interrupt Priority					
					    SPI_INT_PRI_0					
					    SPI_INT_PRI_1					
					    SPI_INT_PRI_2					
					    SPI_INT_PRI_3					
					    SPI_INT_PRI_4					
					    SPI_INT_PRI_5					
					    SPI_INT_PRI_6					
					    SPI_INT_PRI_7
					 
Return Value       : None
 
Remarks            : This function clears the Interrupt Flag bit, sets the
                     interrupt priority and enables/disables the interrupt
