[1] A low level of the BREQ signal is sampled at the rising edge of the Bφ signal.
[2] The bus control signals are driven high at the end of the external space access cycle. It takes two cycles or
[3] The BACK signal is driven low, releasing bus to the external bus master.
[4] The BREQ signal state sampling is continued in the external bus released state.
[5] A high level of the BREQ signal is sampled.
[6] The external bus released cycles are ended one cycle after the BREQ signal is driven high.
[7] When the external space is accessed by an internal bus master during external bus released while the BREQOE
[8] Normally the BREQO signal goes high at the rising edge of the BACK signal.
