ASYNCHRONOUS
NOTES:
3. Timing measurements are referenced to and from a low voltage of 0.8 V and a high voltage of 2.0 V,
2. BR need fall at this time only to insure being recognized at the end of the bus cycle.
1. Setup time for the asynchronous inputs IPL2–IPL0 and AVEC (#47) guarantees their recognition at the
HALT / RESET
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 V and 2.0 V.
