No.
193 RD deassertion to data not valid
194 WR assertion to data active
195 WR deassertion to data high impedance
The number of wait states for out-of-page access is specified in the DCR.
The refresh period is specified in the DCR.
RD deassertion will always occur after CAS deassertion; therefore, the restricted timing is t
The asynchronous delays specified in the expressions are valid for DSP56366.
