cycles. The first address is driven throughout the entire
burst for externally-terminated cycles.
• In multiplexed address/data mode: the address is driven
on FB_AD only during the first cycle for all terminated
cycles. In other words, the lower address lines only
increment during internally-terminated burst cycles
(assuming that the lower address lines are being driven
with the address during the data phase).
