Carry Flag (CF):- When two 8/16 bit number addition the the
result is generate 9/17 bit number then the carry flag is set.
Auxiliary flag (AF):-This flag is active in BCD number.When
Two 8 bit number addition the the carry is generate by D3
bit to D4 bit the the Auxiliary flag is set.
Parity Flag (PF):-This flag is indicate the number is even
or odd.The numbers of one's in result is even 0,2,4,6,8 then
parity flag is set and the number os one's is odd 1,3,5,7
the the parity flag is reset.
Zero Flag (ZF):-This flag is indicate the result is zero or
non-zero.when two 8 bit number addition then the result is
zero then zero flag is set.and the result is non-zero then
the zero flag is reset.
Sign Flag (SF):-This flag is indicate the number is negative
or positive.The MSB in result is one(1)then the sign flag is
set or the result is negative And the MSB in result in
Zero(0) then the sign flag is reset or the result is positive.
