3.9.3 4-, 8-, 16-, 32-, 1K- Word Linear Burst Read Operation During Synchronous Burst Block Read Mode

Same as normal linear burst read, synchronous burst block read 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-, 32- and 1K-words with no wrap. (note that wrap-around is not supported in Synchronous Burst Block Read)

3.9.4 Programmable Burst Read Latency Operation During Synchronous Burst Block Read Mode

Synchronous burst block read mode have programmable burst read latency just same manner as normal synchronous burst read mode.

Upon power up, the number of initial clock cycles from Valid Address (AVD) to initial data defaults to four clocks.

The number of clock cycles (n) which are inserted after the clock which is latching the address. The host can read the first data with the (n+1)th rising edge.

The number of total initial access cycles is programmable from three to seven cycles. After the number of programmed burst clock cycles is reached, the rising edge of the next clock cycle triggers the next burst data.
