6. Bus Controller
6.7.2
After driving the BREQ pin low, hold it low until BACK goes low. If BREQ returns to the high
level before BACK goes lows, the bus arbiter may operate incorrectly.
To terminate the external-bus-released state, hold the BREQ signal high for at least three states. If
BREQ is high for too short an interval, the bus arbiter may operate incorrectly.
