Machine Check Logout Frame - 630/620
The TL6 Machine Check 630/620 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
that are correctable. Machine check logout 630 contains EV6 CPU specific
errors registers while machine check logout 620 contains system specific error
registers.
