[Read Interrupted by Burst Stop]
is minimum 1 CLK. A TERM command to output disable latency is equivalent to the /CAS Latency.
As a result, READ to TERM interval determines valid data length to be output. The figure below
shows examples of BL=8.
Burst read operation can be interrupted by a burst stop command(TERM). READ to TERM interval
