generator polynomial: G(x) = x16 + x12 +x5 + 1,
M(x) = (first bit) * xn + (second bit) * xn-1 +...+ (last bit) * x0
CRC[15...0] = Remainder [(M(x) * x16) / G(x)]
All CRC registers are initialized to zero. The first bit is the first data bit of the corresponding block. The
degree n of the polynomial denotes the number of bits of the data block decreased by one (e.g. n =
4095 for a block length of 512 bytes). The generator polynomial G(x) is a standard CCITT polynomial.
The code has a minimal distance d=4 and is used for a payload length of up to 2048 Bytes (n <=
16383).
