*    Function Name:  ReadRegOC3		                            *
*    Description:    In Non PWM Mode, this function reads the OCRS  *
*                    reg or OCR reg based on input parameter        *
*    Parameters:     char reg                                       *
*    Return Value:   unsigned int OCRS (if reg is 0)                *
*                    or OCR (if reg is 1)                           *
