9-16. Burst Read
This device supports Burst Read.
To set the Burst length, following command operation is required
Issuing command: “C0h” in the first Byte (8-clocks), following 4 clocks defining wrap around enable with “0h” and
disable with“1h”.
Next 4 clocks is to define wrap around depth. Definition as following table:

The wrap around unit is defined within the 256Byte page, with random initial address. It’s defined as “wrap-around
mode disable” for the default state of the device. To exit wrap around, it is required to issue another “C0” command
in which data=‘1xh”. Otherwise, wrap around status will be retained until power down or reset command. To change
wrap around depth, it is requried to issue another “C0” command in which data=“0xh”. “EBh” supports wrap around
feature after wrap around enable. The device id default without Burst read.
