1. Parameter applies to writes of internal E
2
PROM.
2. Either or both of CE1*, CE2* assert according to function truth table.
3. REG* asserted only for Attribute Memory write. REG* must be stable
during the write at the level appropriate to the memory type being accessed.
4. One or both of IWEH*, IWEL* assert per A0, CE1*, CE2*, provided REG* is high.
5. Not shown in timing diagrams.
