/**
  * @brief  Selects the specified I2C PEC position.
  * @param  I2Cx: where x can be 1 or 2 to select the I2C peripheral.
  * @param  I2C_PECPosition: specifies the PEC position.
  *   This parameter can be one of the following values:
  *     @arg I2C_PECPosition_Next: indicates that the next byte is PEC
  *     @arg I2C_PECPosition_Current: indicates that current byte is PEC
  *
  * @note    This function configures the same bit (POS) as I2C_NACKPositionConfig()
  *          but is intended to be used in SMBUS mode while I2C_NACKPositionConfig()
  *          is intended to used in I2C mode.
  *
  * @retval None
