Notes:

1. For a burst length of two, A1-A i selects the two-data-element block; A0 selects the first access within the block.

2. For a burst length of four, A2-A i selects the four-data-element block; A0-A1 selects the first access within the block.

3. For a burst length of eight, A3-A i selects the eight-data- element block; A0-A2 selects the first access within the block.

4. Whenever a boundary of the block is reached within a given sequence above, the following access wraps within the block.

Burst Type

Accesses within a given burst may be programmed to be either sequential or interleaved; this is referred to as the burst type

and is selected via bit A3. The ordering of accesses within a burst is determined by the burst length, the burst type and the start-

ing column address, as shown in Burst Definition on page 11.

Read Latency

The Read latency, or CAS latency, is the delay, in clock cycles, between the registration of a Read command and the availability

of the first burst of output data. The latency can be programmed 2 or 2.5 clocks.

If a Read command is registered at clock edge n, and the latency is m clocks, the data is available nominally coincident with

clock edge n + m.

Reserved states should not be used as unknown operation or incompatibility with future versions may result.
