----------  ---  -----------------------------------------------------------
2010-02-15   ss  Intial version
2011-09-28  rrr  Moved the implementation to CPP, for having BD address being
                 programmed twice if previous BD address was random generated.
2012-02-22  rrr  Added macro related to persistent file path.

  This function is to do the read and write the NV item.

    bIsRandom -> Used only in case of BD address NV item being written.
      bIsRandom = 1 implies that BD address programmed is random generated
      bIsRandom = 0 (default) implies it to be user programmed

  @return  Returns the nagative value on failure.

  @sideeffects Undetermined.
