Full-page Burst Stop
The timing from command input to the last data
changes depending on the CAS 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.
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.
