** ===================================================================
**     Method      :  BitsIoLdd2_GetBit (component BitsIO_LDD)
**
**     Description :
**         Returns the value of the specified bit/pin of the
**         Input/Output component. If the direction is [input] then it
**         reads the input value of the pin and returns it. If the
**         direction is [output] then it returns the last written value
**         (see <Safe mode> property for limitations).
**     Parameters  :
**         NAME            - DESCRIPTION
**       * DeviceDataPtr   - Device data structure
**                           pointer returned by <Init> method.
**         Bit             - Bit/pin number to read
**       * BitVal          - The returned value: 
**                           <false> - logical "0" (Low level)
**                           <true> - logical "1" (High level)
**     Returns     :
**         ---             - Error code, possible values:
**                           ERR_OK - OK
**                           ERR_PARAM_MASK - Invalid pin index
**                           ERR_VALUE - Invalid output parameter
