Note:
1. The minimum number of clock cycles is determined by dividing the minimum time required with clock cycle time
and then rounding off to the next higher integer.
2. Minimum delay is required to complete write.
3. This parameter means minimum

delay at block write cycle only.
4. In case of row precharge interrupt, auto precharge and read burst stop.
