The number of wait states for out-of-page access is specified in the DCR.
The refresh period is specified in the DCR.
The asynchronous delays specified in the expressions are valid for DSP56364.
RD deassertion will always occur after CAS deassertion; therefore, the restricted timing is t
OFF
and not
t
GZ
.
Either t
RCH
or t
RRH
must be satisfied for read cycles.
