Subtraction along with the borrow, here means subtracting value 1 from the subtraction obtained by SUB, if carry (borrow) flag is the set.
The result is stored in the destination operand. All the flags are affected (Condition code) by this instruction. The instance of this instruction is following:
Example :
1. SBB O100H Immediate [destination AX]
2. SBB AX.BX Register
