All exceptions other than a reset are detected in the pipeline ID stage, and accepted at instruction
boundaries. However, an exception is not accepted between a delayed branch instruction and the
delay slot. A re-execution type exception detected in a delay slot is accepted before execution of
the delayed branch instruction. A completion type exception detected in a delayed branch
Pipeline Sequence:
