Full-page Burst Stop
Burst stop command during burst read:
The burst stop (BST) command is used to stop data output during
a full-page burst. The BST command sets the output buffer to High-Z and stops the full-page burst read. The
timing from command input to the last data changes depending on the
CE
latency setting. In addition, the
BST command is valid only during full-page burst mode, and is invalid with burst lengths 1, 2, 4 and 8.
