/*
** ===================================================================
**     Method      :  PWMd_SetRatio16 (bean PWM)
**
**     Description :
**         This method sets a new duty-cycle ratio.
**     Parameters  :
**         NAME       - DESCRIPTION
**         Ratio      - Ratio is expressed as an 16-bit unsigned integer
**                      number. 0 - 65535 value is proportional
**                      to ratio 0 - 100%
**         Note: Calculated duty depends on the timer possibilities
**               and on the selected period.
**     Returns     :
**         ---        - Error code, possible codes:
**                           ERR_OK - OK
**                           ERR_SPEED - This device does not work in

/*
** ===================================================================
**     Method      :  PWMd_SetDutyUS (bean PWM)
**
**     Description :
**         This method sets the new duty value of the output signal. The
**         duty is expressed in microseconds as a 16-bit unsigned integer
**         number.
**     Parameters  :
**         NAME       - DESCRIPTION
**         Time       - Duty to set [in microseconds]
**                      (0 to 20000 us in high speed mode)

**     Description :
**         This method sets the new duty value of the output signal. The
**         duty is expressed in milliseconds as a 16-bit unsigned integer
**         number.
**     Parameters  :
**         NAME       - DESCRIPTION
**         Time       - Duty to set [in milliseconds]
**                      (0 to 20 ms in high speed mode)
