Construction of Flags in 8086
- The Flag Register contains flags in the 8086 processor, which are built like binary indicators such that each flag is represented by a single bit while a specific flag corresponds to each bit and are updated by the Arithmetic logic unit (ALU), when we execute logic or arithmetic instructions.
- For example, if there is a carry out of the most significant bit is set, then the Carry Bit flag (CF) is set while if the result of our operation happens to be none other than zero, then we may as well set the Zero Flag (ZF). In the same manner, they play a significant role when it comes ot controlling how programs run and helping processors to make decisions about information based on them.
