Notes concerning 2CAS 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
Delayed write
Early write
WE
3. Closely separated upper/lower byte control is not allowed. However when the condition (tCP ≤ tUL) is
satisfied, EDO page mode can be performed.
RAS
UCAS
LCAS
t UL
4. Byte control operation by remaining UCAS or LCAS high is guaranteed.
