A status register, flag register, or condition code
register (CCR) is a collection of status flag bits for a processor. An example
is the FLAGS register of the x86 architecture or flags in a program status word
(PSW) register.
The status register is a hardware register that contains
information about the state of the processor. Individual bits are implicitly or
explicitly read and/or written by the machine code instructions executing on
the processor. The status register lets an instruction take action contingent
on the outcome of a previous instruction.
Typically, flags in the status register are modified as
effects of arithmetic and bit manipulation operations. For example, a Z bit may
be set if the result of the operation is zero and cleared if it is nonzero.
Other classes of instructions may also modify the flags to indicate status. For
example, a string instruction may do so to indicate whether the instruction
terminated because it found a match/mismatch or because it found the end of the
string. The flags are read by a subsequent conditional instruction so that the
specified action (depending on the processor, a jump, call, return, or so on)
occurs only if the flags indicate a specified result of the earlier
instruction.
