Carry Flag

CY is  reset  as explained  above.  ( in chapter 1 we have  sen in the 2 complement  methods of subtraction that  the carry  is set  when the result is positive. Here it is  same in step 3  but since  in step 4 microprocessor  complement the  carry flag it is  reset.

In gendered we can say  that after subtraction if the results  is positive  carry flag is reset. And if the  results  is negative carry flag  is set.
