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 SAB 88C166(W) requesting the bus.
2) _{The next SAB 88C166(W) driven bus cycle may start here.}
