START

Setting FFFF (Hex) To CR

CR= CRC error check data (1 word)
I    = Digits of calculation characters 
         in command message
J    = Check on the number of times 
         of CR calculation

Setting 1 to I

Setting 1 to J

CR is shifted by

1 bit to right

Added 1to J

Added 1 to I

END

After shifting CR by 1 bit to right, A001(Hex) and exclusive logical sum

(XOR) are executed for setting the result in CR

Bit at right and of CR is 1?

NO

NO

NO

YES

YES

YES

Eight times of calculation

is completed?

J>8

Calculation of all charactersis completed?

I>All characters numbers

Exclusive logical Sum (XOR) is executed on one character (1 byte) at I

charactor of CR and designated message, and results are set to CR.
