将片内50H~5FH及片外0010H~004FH单元清0；然后将片

内30H~3FH的数据移到片外0000H~000FH中；判断：

若（30H）≤15，则求其平方存到40H中，并将位00H置1

若（30H）=15， 则加15存到40H中，并位01H置1

若（30H）≥15， 则减15存到40H中，并位02H置1 　

-The on-chip and off-chip 50H ~ 5FH 0010H ~ 004FH unit cleared　then slice

The data 30H ~ 3FH moved to chip in 0000H ~ 000FH　judgment:

If (30H) ≤ 15, is seeking to keep its square 40H, and 00H and the bit is set to 1

If (30H) = 15, then add 15 deposit to 40H, and 01H and the bit is set to 1

If (30H) ≥ 15, then subtract 15 deposit to 40H, and 02H and bit set to 1
