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 XC238xA
requesting the bus.
2. The control outputs will be resistive high (pull-up) before being driven inactive (ALE
will be low).
3. The next XC238xA-driven bus cycle may start here.
