Each processor on the CPU has its own CSA (current save area) pointer that points to the MST that is to be used when a thread or interrupt handler is interrupted or swapped due to context switch.
When you issue the 'info locals' command GDB actually prints out variables local to the current frame, which by default is where the interrupted function is (frame 0).
实际上，发出' info locals '命令时，gd b会打印出当前帧中的局部变量，缺省情况下，这个帧中的函数就是被中断的函数(0号帧)。

It and reversing current different is not to be, but with a anode intermittently stop, because the intermittent power supply currentinterrupted, cathode potential with time periodically change.
