Detailed explanation-1: -In 8085 microprocessor, the flags register can have a total of eight flags. Thus a flag can be represented by 1 bit of information. But only five flags are implemented in 8085.
Detailed explanation-2: -There exist total 5 flags (i.e., sign, zero, auxiliary carry, parity and carry flag) in 8085 microprocessor. As against overall 9 flags (i.e., overflow, direction, interrupt, trap and rest other of 8085) are present in 8086 microprocessor.
Detailed explanation-3: -A flag reveals whether a data structure is in a possible state range and may indicate a bit field attribute, which is often permission-related. A microprocessor has multiple state registers that store multiple flag values that serve as possible post-processing condition indicators such as arithmetic overflow.
