 ### Description
 
-### See Also

 The function `update_crc_ccitt()` can be used to calculate the CRC value in a stream of bytes where
 it is not possible to first buffer the stream completely to calculate the CRC when all data
 is received. The parameters are the previous CRC value and the current byte which must be used
