Notes:
1.
The number of wait states for out-of-page access is specified in the DCR.
2.
The refresh period is specified in the DCR.
3.
The asynchronous delays specified in the expressions are valid for DSP56366.
4.
RD deassertion will always occur after CAS deassertion; therefore, the restricted timing is tOFF and not tGZ.
5.
Either tRCH or tRRH must be satisfied for read cycles.
