Flag Registers

Flag  register  is also an  8 bit  register. Out of 8 bit  five are  defined as flags to indicate status  of the accumulator  hence it is also called status register. Flags are  flip  flops  which  can be set or reset.  After  any arithmetical logical  operation some or all flags  are modified according  to the  result  to the   operation. Flag  register  showing  the bit  position  reserved  for various flag  as shown in figure .

The five  flags are sign  flag  (A) zero flag (Z) auxiliary  carry flag (AC) parity flag  (P)and carry  flag(CY).

Important : Flags are  modified  only after any  arithmetical  or logical operation is  performed.
