.
When the aborted bus cycle is an instruction prefetch, the processor will not initiate excep-
tion processing unless the prefetched information is used. For example, if a branch instruc-
tion flushes an aborted prefetch, that word is not accessed, and no exception occurs.
When the aborted bus cycle is a data access, the processor initiates exception processing
immediately, except in the case of released operand writes. Released write bus errors are
delayed until the next instruction boundary or until another operand access is attempted.
Exception processing for bus error exceptions follows the regular sequence, but context
preservation is more involved than for other exceptions because a bus exception can be ini-
