This command makes it possible to write or collate the CRC code in a check
block that the user designates. The CRC code is calculated using the formula
16 12 5
X + X + X + 1 (refer to 3-2-5 DC Memory Check Function ).
M D C/K 1/2 X
M D 0 0
M D C/K 1/2
No.
M D 0 0
No.
Note The number of check block bytes required is the bytes of the check code calcula-
tion area plus two bytes. Refer to 3-2-5 DC Memory Check Function for details.
