Figure 414 Example Halt Indication Cycle from Non-Pipelined Cycle

SHUTDOWN INDICATION CYCLE

The 80376 shuts down as a result of a protection

fault while attempting to process a double fault Sig-

naling its entrance into the shutdown state a shut-

down indication cycle is performed The shutdown

indication cycle is identified by the state of the bus

definition signals shown in Bus Cycle Definition

Signals

and a byte address of 0 The shutdown indi-

cation cycle must be acknowledged by READY as-

serted A shutdown 80376 resumes execution when

NMI or RESET is asserted

ENTERING AND EXITING HOLD

ACKNOWLEDGE

The bus hold acknowledge state Th is entered in

response to the HOLD input being asserted In the

bus hold acknowledge state the 80376 floats all

outputs or bidirectional signals except for HLDA

HLDA is asserted as long as the 80376 remains in

the bus hold acknowledge state In the bus hold ac-

knowledge state all inputs except HOLD and RE-

SET are ignored
