Description: Function name: crc-16 Process
Function prototype: INT16U make_crc16(INT8U *msgaddr,INT8U datalen)
Function: CRC check and generate CRC code. This function only affects the global variable crc16.
The checksum is placed in the end of the string and the low 8 bits are in the top 8.
Msgaddr: the first address of the block for CRC16 check
Datalen: the number of blocks to be checked by CRC16
The calculation algorithm of crc-itu is as follows:
A. The register group is initialized to full "1" (0xFFFF).
B. The register group moves a byte to the right.
C. The first byte that has just been removed is different or operatively from the data byte, and an index of the value table is obtained.
D. The table values indicated by the index are different or operable with the register group.
F. The data pointer is added 1. If the data is not fully processed, repeat step b.
The g. Register group takes the inverse and gets the CRC, which is attached to the data (which can be omitted).
