Quad I/O Word Fast Read with
“8/16/32/64-Byte Wrap Around” in Standard SPI mode
The Quad I/O Word Fast Read command can be used to access a specific portion within a page by issuing
“Set Burst
with Wrap
” (77H) commands prior to E7H. The “Set Burst with Wrap” (77H) command can either enable or disable the
“Wrap Around” feature for the following E7H commands. When “Wrap Around” is enabled, the data being accessed can be
limited to either an 8/16/32/64-byte section of a 256-byte page. The output data starts at the initial address specified in the
command, once it reaches the ending boundary of the 8/16/32/64-byte section, the output will wrap around the beginning
boundary automatically until CS# is pulled high to terminate the command.
The Burst with Wrap feature allows applications that use cache to quickly fetch a critical address and then fill the
cache afterwards within a fixed length (8/16/32/64-byte) of data without issuing multiple read commands. The
“Set Burst
with Wrap
” command allows three “Wrap Bits” W6-W4 to be set. The W4 bit is used to enable or disable the “Wrap Around”
operation while W6-W5 is used to specify the length of the wrap around section within a page.
7.13 Set Burst with Wrap (77H)
The Set Burst with Wrap command is used in conjunction with
“Quad I/O Fast Read” and “Quad I/O Word Fast Read”
command to access a fixed length of 8/16/32/64-byte section within a 256-byte page.
The Set Burst with Wrap command sequence: CS# goes low  Send Set Burst with Wrap command  Send 24
dummy bits  Send 8 bits
“Wrap bits”  CS# goes high.

If the W6-W4 bits are set by the Set Burst with Wrap command, all the following
“Quad I/O Fast Read” and “Quad I/O
Word Fast Read
” command will use the W6-W4 setting to access the 8/16/32/64-byte section within any page. To exit the
“Wrap Around” function and return to normal read operation, another Set Burst with Wrap command should be issued to set
W4=1. In QPI mode, the
“Burst Read with Wrap (0CH)” command should be used to perform the Read Operation with
“Wrap Around” feature. The Wrap Length set by W5-W6 in Standard SPI mode is still valid in QPI mode and can also be
re-configured by
“Set Read Parameters (C0H) command.
