*1 : The output load is 30 pF.
*2 : The output load is 5 pF.
*3 : The tCE is applicable if OE is brought to Low before CE1r goes Low and is also applicable if actual value of both
or either tASO or tCLOL is shorter than specified value.
*4 : Applicable only to A0 and A1 when both CE1r and OE are kept at Low for the address access.
*5 : Applicable if OE is brought to Low before CE1r goes Low.
*6 : The tASO, tCLOL(Min) and tOP(Min) are reference values when the access time is determined by tOE.
If actual value of each parameter is shorter than specified minimum value, tOE become longer by the amount of
subtracting actual value from specified minimum value.
For example, if actual tASO, tASO(actual), is shorter than specified minimum value, tASO(Min), during OE control
access (ie., CE1r stays Low), the tOE become tOE(Max) + tASO(Min) – tASO(actual).
*7 : The tASO(ABS) and tOP(ABS) is the absolute minimum value during OE control access.
*8 : The tAX is applicable when both A0 and A1 are switched from previous state.
*9 : If actual value of either tCLOL or tOP is shorter than specified minimum value, both tOLAH and tOLCH become tRC(Min) –
tCLOL(actual) or tRC(Min) – tOP(actual).
*10 : Maximum value is applicable if CE1r is kept at Low.
