Table 8.6
through
Table 8.8
show the address/boundary crossing latency for variable wait state if a boundary
crossing occurs during initial access
The device will continue to output continuous, sequential burst data, wrapping around to address 000000h
after it reaches the highest addressable memory location, until the system asserts CE# high, RESET# low, or
AVD# low in conjunction with a new address. See
Table 8.1 on page 14
. The reset command does
not
terminate the burst read operation.
If the host system crosses a 128 word line boundary while reading in burst mode, and the device is not
programming or erasing, no additional latency will occur as described above. If the host system crosses the
bank boundary while the device is programming or erasing, the device will provide asynchronous read status
information. The clock will be ignored. After the host has completed status reads, or the device has completed
the program or erase operation, the host can restart a burst operation using a new address and AVD# pulse.
