1. Status register

   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. Some CPU architectures, such as the MIPS and Alpha, do not use a dedicated flag register. Others do not implicitly set and/or read flags. Such machines either do not pass implicit status information between instructions at all, or they pass it in an explicitly selected general purpose register. A status register may often have other fields as well, such as more specialized flags, interrupt enable bits, and similar types of information. During an interrupt, the status of the thread currently executing can be preserved (and later recalled) by storing the current value of the status register along with the program counter and other active registers into the machine stack or some other reserved area of memory.

1. status register

   A status register refers to a small, reserved memory location within a computer system or microprocessor that stores the outcome or result of a particular operation, condition, or flag. It is often a part of the processor's architecture and contains status bits that can be set or cleared based on specific events or conditions encountered during program execution. These bits can be used to indicate the current state of the processor or to influence subsequent instructions and program flow. The status register allows the processor to keep track of important information and make decisions based on the status of previous operations.
