Word Read Quad I/O with “8/16/32/64-Byte Wrap Around”
The Word Read Quad I/O instruction can also be used to access a specific portion within a page by issuing a
“Set Burst with Wrap” command prior to E7h. The “Set Burst with Wrap” 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 a 8, 16, 32 or 64-byte section of a 256-byte page. The output
data starts at the initial address specified in the instruction, once it reaches the ending boundary of the
8/16/32/64-byte section, the output will wrap around to 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” instruction allows three “Wrap Bits”, W6-4 to be set. The W4 bit is used to enable
or disable the “Wrap Around” operation while W6-5 are used to specify the length of the wrap around section
within a page. See
