216 / 818 page  Section 6 Bus Controller Rev.3.00 Mar. 26, 2007 Page 174 of 772 REJ09B0355-0300 6.8.4 Transition Timing Figure 6.23 shows the timing for transition to the bus-released state. CPU cycle External bus released state CPU cycle Address Minimum 1 state T0 T1 T2 φ Address bus Data bus AS HWR, LWR BREQ BACK High impedance [1] [2] [3] [4] [5] [1] Low level of BREQ pin is sampled at rise of T 2 state. [2] BACK pin is driven low at end of CPU read cycle, releasing bus to external bus master. [3] BREQ pin state is still sampled in external bus released state. [4] High level of BREQ pin is sampled. [5] BACK pin is driven high, ending bus release cycle. High impedance High impedance High impedance RD High impedance Figure 6.23 Bus-Released State Transition Timing |
