words latched during the bus cycle. If the cycle is for a data fetch, the bus
error exception is taken immediately. Refer to SECTION 11 INSTRUCTION
When a bus error occurs after the burst mode has been entered (that is, on
the second access or later), the processor terminates the burst operation,
EXECUTION TIMING for more information about pipeline operation.
and the cache entry corresponding to that cycle is marked invalid, but the
processor does not take an exception (see Figure 7-52). If the second cycle
is for a portion of a misaligned operand fetch, the processor runs another
