Data out
If the clock input is halted during burst read operation, the data output will be suspended. During the burst read
suspend period, OE# high drives data output to high-Z. If the clock input is resumed, the suspended data will be
output first.
/WAIT Low (t
/WAIT High (t
/WAIT High-Z (t
During the suspend period, OE# high drives DQ to High-Z and OE# low drives DQ to Low-Z. If OE# stays low during
suspend period, the previous data will be sustained.
