(1) CRC = CRC XOR Object data(1B)
(1-1) A=CRC AND "0001"
CRC= shift 1bit right of CRC
(1-1) If A=1, CRC XOR Generating
polynomial, and assign the result to
CRC.
If A=0, do nothing
(2-1) Calculate the same as (1-1), and
repeat (1-1) and (1-2) calculation seven
times. (8bits in total)
(2-2) Calculate the same as (1-2). CRC is as
it is since A=0.
(3-1) Calculation the same as (1-1).
(3-2) Calculate the same as (1-2).
(4-1) Calculation the same as (1-1).
(4-2) Calculate the same as (1-2).
(5-1) Calculate the same as (1-1).
(5-2) Calculate the same as (1-2).
(6-1) Calculate the same as (1-1).
(6-2) Calculate the same as (1-2).
(7-1) Calculate the same as (1-1).
(7-2) Calculate the same as (1-2).
(8-1) Calculate the same as (1-1).
(8-2) Calculate the same as (1-2).
CRC calculation for "1B" is completed.
Repeat the same calculation of (1) for next
object data "41" until "03". In this case EC
5E.
