NOTES:
1. Setup time for the asynchronous inputs IPL2–IPL0 guarantees their recognition at the next falling edge of
the clock.
2. BR need fall at this time only to insure being recognized at the end of the bus cycle.
3. Timing measurements are referenced to and from a low voltage of 0.8 volt and a high voltage of 2.0 volts,
unless otherwise noted. The voltage swing through this range should start outside and pass through the
range such that the rise or fall is linear between 0.8 volts and 2.0 volts.
