Transition Timing
Note: The refresh control function is not supported by the 5-V version.
[1] Low level of BREQ signal is sampled at rise of φ.
[2] Bus control signal returns to be high at end of external space access cycle.
[3] BACK signal is driven low, releasing bus to external bus master.
[4] BREQ signal state is also sampled in external bus released state.
[5] High level of BREQ signal is sampled.
[6] BACK signal is driven high, ending external bus release cycle.
