BURST Termination
There are two methods to terminate a burst operation other than using a read or a write command. One is the burst stop
command and the other is the precharge command.
BURST Stop Command
During a read burst, when the burst stop command is issued, the burst read data are terminated and the data bus goes to
high-impedance after the CAS latency from the burst stop command.
During a write burst, when the burst stop command is issued, the burst write data are termained and data bus goes to Hi-
Z at the same clock with the burst stop command.
