The processor also halts if it receives a bus error or address error during the
vector table read operations or the prefetch for the first instruction after an
conditions, which include MMU address translation cache miss, reset, bus
error, address error, spurious interrupt, autovectored interrupt, and F-line
STATUS to assert for three clock cycles to indicate that normal instruction
case since these exceptions are processed immediately, not just at instruction
Figure 12-22 shows the assertion of STATUS, indicating that the processor
has halted due to a double bus fault. Once a bus error has occurred, any
additional bus error exception occurring before the execution of the first
instruction of the bus error handler routine constitutes a double bus fault.

Figure 12-21 illustrates the assertion of the STATUS signal for other exception
instruction when no coprocessor responds. Exception processing causes
