MAIN MEMORY WRITE CYCLE *1
ATTRIBUTE MEMORY WRITE CYCLE *4
Notes:
*1.
If OE, CE
1
, and CE
2
are in the Read Mode during this period, then the I/O pins are in the output state
and the input signals of the phase opposite to the outputs must be applied.
Transition is measured at the point of
±
500 mV from steady state voltage.
This parameter is specified only during write cycle with OE = V
IL
and specified using Load II in Fig.3.
This parameter is for MB98A90833, 90933, 91033 and 91133.
