Figure 81 : 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
(On P6.x)
is initiated by HOLD going high. Please note that HOLD may also be deactivated without the ST10F269 requesting the bus.
2. The next ST10F269 driven bus cycle may start here.
