4.6.2 Machine Check Logout Frames
Machine Check Logout Frame - 670/660
The TL6 Machine Check 670/660 logout frame provides error information to the
operating system error handler. When a fault is detected, PALcode enters a
error handler, captures the state of the processor and system, and builds a
logout frame. One frame is built for both processor and system detected errors.
Machine check logout 670 contain EV6 CPU specific error registers while
machine check logout 660 contains system specific error registers.
