Revision 1.0
to the next data will be latched (in burst accesses). This parameter can also be thought of as the delay between the ris-
ing edge of TClk which data is latched to the rising edge of TClk where the next data is latched in a burst cycle. This
parameter can be extended by the Ready* pin.

ADStoWr, bits[13:11]
There are eight byte write signals, four for even bank devices (EWr[3:0]*) and four for odd bank devices (OWr[3:0]*).
ADStoWr can also be thought as the delay between the rising edge of TClk which drives ADS* LOW (ALE HIGH) from
to the assertion of EWr* or OWr*, or for the first write pulse.
5.2.5
WrActive, bits[16:14]
WrActive is the number of TClks that EWr* and OWr* are active (asserted). This parameter is measured from the first
rising edge of TClk where EWr* or OWr* is asserted LOW to the last rising edge of TClk where EWr* or OWr* is LOW
for that particular write pulse. This parameter can be extended by the Ready* pin.
5.2.6
WrHigh, bits[19:17]
WrHigh is the number of TClks that EWr* and OWr* are inactive between burst writes. This parameter is measured
from the first rising edge of TClk where EWr* or OWr* is de-asserted HIGH to the last rising edge of TClk where EWr*
or OWr* is HIGH. On the next rising edge of TClk, EWr* and OWr* will be asserted LOW for the next write pulse.
These signals are driven off of the falling edge of TClk.
