** Method : M_1_SetRatio16 (component PWM)
** Description :
** This method sets a new duty-cycle ratio. Ratio is expressed

** proportional to ratio 0 - 100%. The method is available
** only if it is not selected list of predefined values in
** <Starting pulse width> property.
** Note: Calculated duty depends on the timer possibilities and
** on the selected period.
** Parameters :
** NAME - DESCRIPTION
** Ratio - Ratio to set. 0 - 65535 value is
** proportional to ratio 0 - 100%
** Returns :
** --- - Error code, possible codes:
** ERR_OK - OK
