Tell me are all the bits of flag register used in 8051?
Submitted by: Muhammad☛ The flag register also called as the program status word uses only 6 bits.
☛ The two unused bits are user defineable flags.
☛ Carry, auxillary carry, parity and overflow flags are the conditional flags used in it.
☛ PSW.1 is a user definable bit and PSW.5 can be used as general purpose bit.
☛ Rest all flags indicate some or the other condition of an arithmetic operation.
