Burst Stop
Burst stop command during burst read
The burst stop (BST) command is used to stop data output during a burst read. The BST command stops the burst
read and sets the output buffer to High-Z. tBSTZ (= CL) cycles after a BST command issued, the DQ pins become
High-Z. The BST command is not supported for the burst write operation. Note that bank address is not referred
when this command is executed.
