Figure 27: 4-Word Burst READ Operation - Fixed Latency
Notes :
1. Non-default BCR settings: Fixed latency; latency code two (three clocks); WAIT active LOW; WAIT asserted during delay.
2. WAIT will remain de-asserted even if CE# remains LOW past the end of the defined burst length.
3. A/DQ[15:0] will output undefined data if CE# remains LOW past the end of the defined burst length.
