Section 12 DDR-SDRAM Interface (DDRIF)

Figures 12.5 to 12.14 show basic timing of the DDRIF.

In each timing chart, the DDR-SRAM has been idle at T0.

The settings in the SDRAM timing register (STR) must set up timing that is within the

specifications of the DDR-SDRAM.

Note that the only CAS latency supported by the DDRIF is 2.5.
