Function Prototype : void ConfigIntCN(unsigned int config)
 
Include            : ports.h
 
Description        : This function configures the CN interrupts.
 
Arguments          :  config - CN interrupt priority and enable/disable information 
                     as defined below
                     CN Interrupt enable/disable
					   INT_ENABLE
					   INT_DISABLE
					 CN Interrupt priority
                       INT_PRI_0
                       INT_PRI_1
                       .....
                       INT_PRI_6
                       INT_PRI_7
 
Return Value       : None
 
Remarks            : This function clears the Interrupt Flag bit and then sets
                     the interrupt priority and enables/disables the interrupt.
