Note 21: The output propagation delay is referenced to the end of the instruction cycle where the output change occurs.

Note 22: Parameter characterized but not tested.

Note 23: Rise times faster than the minimum specification may trigger an internal power-on-reset.

Note 24: Exclusive of R and C variation.

Note 25: MICROWIRE Setup and Hold Times and Propagation Delays are referenced to the appropriate edge of the MICROWIRE clock. See
