10-14. Burst Read

The Burst Read feature allows applications to fill a cache line with a fixed length of data without using multiple

read commands. Burst Read is disabled by default at power-up or reset. Burst Read is enabled by setting

the Burst Length. When the Burst Length is set, reads will wrap on the selected boundary (8/16/32/64-bytes)

containing the initial target address. For example if an 8-byte Wrap Depth is selected, reads will wrap on the

8-byte-page-aligned boundary containing the initial read address.

To set the Burst Length, drive CS# low → send SET BURST LENGTH instruction code → send WRAP CODE →

drive CS# high. Refer to the table below for valid 8-bit Wrap Codes and their corresponding Wrap Depth.

Once Burst Read is enabled, it will remain enabled until the device is power-cycled or reset. The 4READ read

command supports the wrap around feature after Burst Read is enabled. To change the wrap depth, resend the

Burst Read instruction with the appropriate Wrap Code. To disable Burst Read, send the Burst Read instruction

with Wrap Code 1xh. “EBh" supports wrap around feature after wrap around is enabled.
