* Function Name: Crc_CalculateCRC8
*
* Description:   This service makes a CRC8 calculation on Crc_Length data bytes, with SAE J1850 parameters.
*
*
* Inputs:        Crc_DataPtr          Pointer to start address of data block to be calculated.
*                Crc_Length           Length of data block to be calculated in bytes.
*                Crc_StartValue8      Start value when the algorithm starts.
*                Crc_IsFirstCall      TRUE: First call in a sequence or individual CRC calculation;
*                                          start from initial value, ignore Crc_StartValue8.
*                                     FALSE: Subsequent call in a call sequence; Crc_StartValue8
*                                     is interpreted to be the return value of the previous function call.
*
* Outputs:       uint32:   8 bit result of CRC calculation.
*
* Limitations:   None
