3.7.2.1 Continuous Linear Burst Read Operation

See Timing Diagram 6.2

First Clock Cycle

The initial word is output at tIAA after the rising edge of the first CLK cycle. The RDY output indicates the initial word is ready to the system by pulsing high. If the device is accessed synchronously while it is set to Asynchronous Read Mode, the first data can still be read out.

Subsequent Clock Cycles

Subsequent words are output (Burst Access Time from Valid Clock to Output) tBA after the rising edge of each successive clock cycle, which automatically increments the internal address counter.

Terminating Burst Read

The device will continue to output sequential burst data until the system asserts CE high, or RP low, wrapping around until it reaches the des- ignated address (see section 2.7.3 for address map information). Alternately, a Cold/Warm/Hot Reset, or a WE low pulse will terminate the burst read operation.

3.7.2.2 4-, 8-, 16-, 32-Word Linear Burst Read Operation

See Timing Diagram 6.1

An alternate Burst Read Mode enables a fixed number of words to be read from consecutive address.

The device supports a burst read from consecutive addresses of 4-, 8-, 16-, and 32-words with a linear-wrap around. When the last word in the burst has been reached, assert CE and OE high to terminate the operation.

In this mode, the start address for the burst read can be any address of the address map with one exception. The device does not support a 32-word linear burst read on the spare area of the BufferRAM.
