Function Prototype : void ConfigIntTimer23(unsigned int config)

Include            : timer.h
 
Description        : This function configures the 32-bit timer interrupt.
 
Arguments          : config - Timer interrupt priority and enable/disable 
                     information as defined below
                     Timer Interrupt Priority
					   T23_INT_PRIOR_7					
					   T23_INT_PRIOR_6					
					   T23_INT_PRIOR_5					
					   T23_INT_PRIOR_4					
					   T23_INT_PRIOR_3					
					   T23_INT_PRIOR_2					
					   T23_INT_PRIOR_1					
					   T23_INT_PRIOR_0
					  Timer Interrupt Enable\Disable 					
					   T23_INT_ON					
					   T23_INT_OFF
					 
Return Value      : None
 
Remarks           : This function clears the Interrupt Flag (TxIF) bit 
                    and then sets the interrupt priority and enables/disables 
                    the interrupt.
