Notes: 1. If the fall of
CSn
is later than the fall of
WEn
, the specifications of t
ADS
, t
RDHW
, and t
WAS2
are from the fall of
CSn
. (
CSn
=
CS0
,
CS1
.
WEn
=
WE0
,
WE1
.)
2. If the rise of
CSn
is earlier than the rise of
WEn
, the specifications of t
ADH
, t
RDHW
, t
WRDES
,
t
WRDH
, and t
WRDOF
are from the rise of
CSn
. (
CSn
=
CS0
,
CS1
.
WEn
=
WE0
,
WE1
.)
