In Figure 78 on page 192, a shutdown (triple fault) occurs in the
first half of the waveform, and a shutdown special cycle follows
in the second half. The processor enters shutdown when an
interrupt or exception occurs during the handling of a double
fault (INT 8), which amounts to a triple fault. When the
processor encounters a triple fault, it stops its activity on the
bus and generates the shutdown special bus cycle (BE[7:0]# =
The system logic must assert NMI, INIT, RESET, or SMI# to get
the processor out of the shutdown state.
