5 4 6 Shutdown Indication Cycle
The Intel386 DX shuts down as a result of a protec-
tion fault while attempting to process a double fault
Signaling its entrance into the shutdown state a
shutdown indication cycle is performed The shut-
down indication cycle is identified by the state of the
bus definition signals shown in 5 2 5 Bus Cycle Def-
inition and a byte address of 0 BE0
Figure 5-24 Shutdown Indication Cycle
and BE2
are the only signals distinguishing shutdown indica-
tion from halt indication which drives an address of
2 During the shutdown cycle undefined data is driv-
en on D0 – D31 The shutdown indication cycle must
be acknowledged by READY
