Notes
External Bus Arbitration, Regaining the Bus
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 XC228x requesting
the bus.
2. The control outputs will be resistive high (pull-up) before being driven inactive (ALE
will be low).
3. The next XC228x driven bus cycle may start here.
