The TCB is used by the OS to manage the task. Refer to your processor user manual to find out how interrupts are acknowledged. It may be that the hardware saves some context on the stack of the interrupted thread, e.g. flags, instruction pointer. In some operating systems, a Process Control Block (PCB), sometimes known as a Task Control Block (TCB), is a data structure that stores and maintains critical process information. It serves as a central repository for information relevant to a specific process, allowing the operating system to manage and control process execution more effectively.
