Write Interrupted by a Write

A Burst Write can be interrupted before completion of the burst by a new Write command, with the only restriction that the interval that

separates the commands must be at least one clock cycle. When the previous burst is interrupted, the remaining addresses are

overridden by the new address and data will be written into the device until the programmed burst length is satisfied.
