12. Burst Termination
burst stop command and the other is the precharge command.
12.1 Burst Stop Command
goes to Hi-Z after the /CAS latency from the burst stop command.

to Hi-Z at the same clock with the burst stop command.
Remark BST: Burst stop command
There are two methods to terminate a burst operation other than using a Read or a Write command. One is the
During a read cycle, when the burst stop command is issued, the burst read data are terminated and the data bus
During a write cycle, when the burst stop command is issued, the burst write data are terminated and data bus goes
/CAS latency = 2, 3
/CAS latency = 2
/CAS latency = 3
