Sleep Mode
1. X = “Don't Care.” H = Logic HIGH, L = Logic LOW. BW
2. Write is defined by BW
3. When a Write cycle is detected, all IOs are tri-stated, even during Byte Writes.
4. The DQs and DQP
5. CEN = H, inserts wait states.
6. Device powers up deselected with the IOs in a tri-state condition, regardless of OE.
7. OE is asynchronous and is not sampled with the clock rise. It is masked internally during write cycles. During a read cycle DQs and DQP
are asserted, see section
