1. Q
01
refers to output from address A. Q
02
refers to output from the next internal burst address following A, etc.
2. Outputs are disabled (High-Z) one clock cycle after a NOP.
3. The second NOP cycle is not necessary for correct device operation; however, at high clock frequencies, it may be required to prevent
bus contention.
