No.
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
Reduced DSP clock speed allows use of DRAM out-of-page access with four Wait states (See
time)
