Bus Operation
4.5.4 Double Bus Fault
A double bus fault results when a bus error or an address error occurs during the exception
processing sequence for any of the following:
For example, the QUICC attempts to stack several words containing information about the
state of the machine while processing a bus error exception. If a bus error exception occurs
during the stacking operation, the second error is considered a double bus fault. When a
double bus fault occurs, the QUICC halts and drives the HALT line low. Only a reset opera-
tion can restart a halted QUICC. However, bus arbitration can still occur (refer to 4.6 Bus
Arbitration). A second bus error or address error that occurs after exception processing has
4-48
1. A previous bus error
2. A previous address error
3. A reset
