31) CRC CALCULATION
This protocol includes 2 byte CRC-16 in all the transmission. The typical polynomial
(11000000000000101B) is used for the calculation and the result is “hanged up” at the end
of the packet. The polynomial is used in reverse order with the more significant bit elimi-
nated because useless for the calculation.
32) PARAMETERS DESCRIPTION
A - 16bit register
AL - A lower part
AH - A upper part
i,j, - COUNTERS
(+) - EXCLUSIVE OR
Di - frame datum (thousandth) of the packet
N - byte number of the packet, excluded the 2 of CRC
G - Polynomial : 1010-0000-0000-0001
shr - shift to the right
33) ALGORITHM
1) 0xFFFF -> A
2) 0 -> i
3) 0 -> j
4) Di (+) AL -> AL
5) j +1 -> j
6) shr A
7) if carry then G (+) A -> A
8) if NOT j=8 then go to 5
9) i +1 -> i
10) if NOT i = N then go to 3
11) A -> in CRC (the result is in the L,H)
