Notes concerning 2
CAS
control
Please do not separate the
UCAS
/
LCAS
operation timing intentionally. However skew between
UCAS
/
LCAS
are allowed under the following conditions.
1. Each of the
UCAS
/
LCAS
should satisfy the timing specifications individually.
2. Different operation mode for upper/lower byte is not allowed; such as following.
RAS
UCAS
LCAS
WE
Delayed write
Early write
3. Closely separated upper/lower byte control is not allowed. However when the condition (t
CP
t
UL
) is
satisfied, EDO page mode can be performed.
RAS
UCAS
LCAS
tUL
4. Byte control operation by remaining
UCAS
or
LCAS
high is guaranteed.
