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
Either t
CAS assertion to data not valid (write)
RAS assertion to data not valid (write)
WR assertion to CAS assertion
CAS assertion to RAS assertion (refresh)
RAS deassertion to CAS assertion (refresh)
