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 (e.g., t
PC equals 4 × TC for
read-after-read or write-after-write sequences).
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 will always occur after CAS deassertion; therefore, the restricted timing is t
OFF and not tGZ.
