WebOn some processors, the status register also contains flags such as these: CPU architectures without arithmetic flags[edit] Status flags enable an instruction to act based on the result of a previous instruction. WebThe two status registers have 16 bits and are called the instruction pointer (IP) and the flag register (F): • IP, which is the instruction pointer. The IP register contains the address of the next instruction of the program. • Flag register. The flag register holds a collection of 16 different conditions. Table 14.1 outlines the most used flags.
