**     Method      :  AdcFD_EnableIntTrigger (bean ADC)
**
**     Description :
**         Enables the internal trigger mode. A conversion of all
**         channels will be launched by internal sync pulse. If the
**         <Number of conversions> is greater than 1, a conversion
**         will be launched more than once (by an internal signal)
**         according to <Number of conversions>. It's possible to
**         disable the trigger mode by <Stop> method. This
**         EnableIntTrigger method is available only when the
**         <Internal trigger> property is enabled.
**     Parameters  : None
**     Returns     :
**         ---             - Error code, possible codes:
**                           ERR_OK - OK
