output data
Note: 1. The minimum number of clock cycles is determined by dividing the minimum time required with
Transcend information Inc
2. Minimum delay is required to complete write.
3. All parts allow every cycle column address change.
4. In case of row precharge interrupt, auto precharge and read burst stop.
