WebOct 25, 2013 · The CRC/16 algorithm treats all 1024 data bits in an Xmodem packet as an integer, multiples that integer by 2^16 and then divides that 1040 bit number by a 17 bit prime number. The low order 16 bits of the remainder becomes the 16 bit CRC. The 17 bit prime number in CRC Xmodem is 216 + 212 + 25 + 1 or 65536 + 4096 + 32 + 1 = 69665.
