Figure 13: Register READ, Synchronous Mode, Followed by READ ARRAY Operation (WE# HIGH)
Note:
1. Non-default BCR settings for synchronous mode register READ followed by READ ARRAY operation: Latency code 2 (3 clocks);
2. A[19:18] = 00b to read RCR, 10b to read BCR, and 01b to read DIDR.
3. CE# must remain LOW to complete a burst-of-one READ. WAIT must be monitored; additional WAIT cycles caused by refresh collisions require
a corresponding number of additional CE# LOW cycles.
WAIT active LOW; WAIT asserted during delay.
