/********************************************************************
*    Function Name:  SetOutputPWM1                                  *
*    Return Value:   void                                           *
*    Parameters:     outputconfig: holds PWM output configuration.  *
*                    These configurations are defined in pwm.h.     *
*                    outputmode: holds PWM output mode.             *
*                    These modes are defined in pwm.h.              *
*    Description:    This routine sets the PWM output config bits   *
*                    and mode bits for ECCP and configures the      *
*                    appropriate TRIS bits for output.              *
