Which type of CRC 16 is used in following string? Before CRC - 80 01 F0, and after CRC : 80 01 F0 23 80. How do I get those two bytes: 23 80?
In documentation written:
Low and high byte of a forward CRC-16 algorithm using the Polynomial (X16 + X15 + X2 + 1) calculated on all bytes. It is initialised using the seed 0xFFFF. The CRC is calculated before byte stuffing.

Can somebody expain step by step what is going on there?
