Figure 25 External Bus Arbitration, Regaining the Bus
Notes
1. This is the last chance for BREQ
to trigger the indicated regain-sequence.
Even if BREQ
is activated earlier, the regain-sequence is initiated by HOLD going
high. Please note that HOLD
may also be deactivated without the XC167 requesting
the bus.
2. The control outputs will be resistive high (pull-up) before being driven inactive (ALE
will be low).
3. The next XC167 driven bus cycle may start here.
