5.
To make I/Os to Hi-Z in read cycle, it is necessary to control RAS, CAS, WE, OE as follows. The effective
specification depends on state of each signal.
(1)
Both RAS and CAS are inactive (at the end of the read cycle)
WE: inactive, OE: active
t
OFC
is effective when RAS is inactivated before CAS is inactivated.
t
OFR
is effective when CAS is inactivated before RAS is inactivated.
The slower of t
OFC
and t
OFR
becomes effective.
(2)
Both RAS and CAS are active or either RAS or CAS is active (in read cycle)
WE, OE: inactive ······ t
OEZ
is effective.
Both RAS and CAS are inactive or RAS is active and CAS is inactive (at the end of read cycle)
WE, OE: active and either t
RRH
or t
RCH
must be met ······ t
WEZ
and t
WPZ
are effective.
The faster of t
OEZ
and t
WEZ
becomes effective.
The faster of (1) and (2) becomes effective.
