static

Calculates the CRC16 checksum of an array by using a table.

The crc16 polynomial is 0x1021 ( x^16 + x^12 + x^5 + 1 ). This function takes 0xffff as initial value.

Note: The checksum generated by this function is NOT according to CCITT standard!

Parameters

*data	Points to the byte array from which checksum should be calculated
size	Size of the byte array
