The 16-bit CRC checksum. The algorithm used is CRC-CCITT. The CRC calcula-

tion includes all bytes of the frame. The data bytes have to be calculated as a

word. At first you have to shift in the high byte of the data word. This is the opposite

way you transmit the data word. The 16-bit generator polynomial ‘x16

+x12

+x5

+1’ is

used for the calculation.
