Burst Wrap (BW)
CR.3 sets the burst wrap. The burst wrap determines how the device will handle a burst-mode read
that crosses a 16-word row boundary. Wrap can be set to have either the burst mode wrap around to
the same row or have the burst read consecutive addresses.
Wrap applies to 4- and 8-word burst modes only. Wrap has no effect in continuous burst mode. In
4- and 8-word burst mode with wrap enabled, the WAIT signal will not be asserted. In 4- and 8-
word burst mode with wrap disabled, the WAIT signal will be asserted only if a 16-word row
boundary is crossed.

CR.2
–
CR.0 sets the burst length. The burst length determines the maximum number of consecutive
words the device will output during a burst-mode read. 1.8 Volt Intel
Wireless Flash Memory with
3 Volt I/O supports 4-, 8- and continuous-word burst lengths.
4.3
Read Query Register
The query plane comes to the foreground and occupies a 4-Mbit address range at the partition
supplied by the Read Query command address. The mode outputs Common Flash Interface (CFI)
data when partition addresses are read.
Appendix C,
“
Common Flash Interface
”
on page 68
shows
query mode information and addresses. Issuing a Read Query command to a partition that is
programming or erasing places that partition
’
s outputs in read query mode while the partition
continues to program or erase in the background. The Read Query command is subject to read
restrictions dependent on the parameter partition availability. Refer to
Table 15,
“
Simultaneous
Operations Allowed with the Protection Register
”
on page 32
for details.
4.4
Read ID Register
The Identification (ID) Register contains various product information, such as manufacturer ID,
device ID, block lock status, protection register information, and configuration register settings. To
obtain any information from the ID register, execute the Read ID Register command. Information
contained in this register can only be accessed by executing a single-word asynchronous read.
