Flag is an 8-bit register, called the flag register,
adjacent to the accumulator. However, it is not used as a
register; five bit positions out of eight are used to store
the outputs of the five flip-flops. The flags are stored in
the 8-bit register so that the programmer can examine these
flags (data conditions) by accessing the register through
an instruction.These flags have critical importance in the
decision-making process of the microprocessor. The
conditions (set or reset) of the flags are tested through
the software instructions.
