latency is specified as two cycles or more, the Tnop cycle is not inserted because the two cycles of

latency can be acquired even if the DQMxx signal is asserted after the Tc cycle.

When bank active mode is set, if only access cycles to the respective banks in the area 3 space are

considered, as long as access cycles to the same row address continue, the operation starts with the

cycle in figure 8.19 or 8.23, followed by repetition of the cycle in figure 8.20 or 8.23. An access to

a different area during this time has no effect. If there is an access to a different row address in the

bank active state, after this is detected the bus cycle in figure 8.20 or 8.23 is executed instead of

that in figure 8.21 or 8.24. In bank active mode, too, all banks become inactive after a refresh

cycle or after the bus is released as the result of bus arbitration.

Notes: 1. Address pin to be connected to pin A10 of SDRAM.

2. The waveform for DACKn is when active low is specified.
