1. A[19:18] = 00b to load RCR, and 10b to load BCR.
1. Non-default BCR settings for synchronous mode configuration register WRITE followed by READ ARRAY operation: Latency
2. A[19:18] = 00b to load RCR, and 10b to load BCR.
3. CE# must remain LOW to complete a burst-of-one WRITE. WAIT must be monitored—additional WAIT cycles caused by refresh
