1 The number of wait states for Page mode 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 DSP56367.
4 All the timings are calculated for the worst case. Some of the timings are better for specific cases (for example, t
PC equals
3
× TC for read-after-read or write-after-write sequences). An expressions is used to calculate the maximum or minimum
value listed, as appropriate.
5 BRW[1–0] (DRAM control register bits) defines the number of wait states that should be inserted in each DRAM out-of-page
access.
6 RD deassertion always occurs after CAS deassertion; therefore, the restricted timing is t
OFF and not tGZ.
