Set Burst with Wrap (77H)

See Figure 18, The Set Burst with Wrap instruction is used in conjunction with “Quad I/O Fast Read” and

“Quad I/O Word Fast Read” instruction to access a fixed length of 8/16/32/64-byte section within a 256-byte

page, in standard SPI mode.

The Set Burst with Wrap instruction sequence:/CS goes low ->Send Set Burst with Wrap instruction

->Send24 Dummy bits ->Send 8 bits “Wrap bits”->/CS goes high.

If W6-4 is set by a Set Burst with Wrap instruction, all the following “Fast Read Quad I/O” and “Word Read

Quad I/O” instructions will use the W6-4 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

instruction should be issued to set W4=1. The default value of W4 upon power on is 1.

W4 = 0

W4 =1 (DEFAULT)
