Table 2-11.
The number of wait states for an out-of-page access is specified in the DRAM Control Register.
The refresh period is specified in the DRAM Control Register.
Use the expression to compute the maximum or minimum value listed (or both if the expression includes ±) .
Either t
RD deassertion always occurs after CAS deassertion; therefore, the restricted timing is t
