Include            : outcompare.h
 
Description        : This function configures the Output Compare module.
 
Arguments          : config - This contains the parameters to be configured in the
					 OCxCON register as defined below					
					 Idle mode operation					
					   OC_IDLE_STOP					
					   OC_IDLE_CON					
					 Clock select					
					   OC_TIMER2_SRC					
					   OC_TIMER3_SRC					
					 Output Compare modes of operation					
					   OC_PWM_FAULT_PIN_ENABLE					
					   OC_PWM_FAULT_PIN_DISABLE					
					   OC_CONTINUE_PULSE					
					   OC_SINGLE_PULSE					
					   OC_TOGGLE_PULSE					
					   OC_HIGH_LOW					
					   OC_LOW_HIGH					
					   OC_OFF					
					 value1 - This contains the value to be stored into OCxRS Secondary					
					 Register.
					 [Note: In single compare mode, user may set this parameter 'value1' as 0x0000]					
					 value2 - This contains the value to be stored into OCxR Main					
					 Register
 
Return Value       : None
 
Remarks            : This function configures the Output Compare Module Control register
                     (OCxCON)with the following parameters:
                      Clock select, mode of operation, operation in Idle mode.
                      It also configures the OCxRS and OCxR registers.
