Supported Commands
3-Port EBI Configuration
4-Port EBI Configuration
The SDRAM commands that are supported by the EBI is listed in
Table 24-3.
When 3 EBI ports are available, SDRAM can be connected with 3-Port EBI configuration. When
this is done only 4-bit data bus is available, and any chip select must be controlled from software
using a general purpose I/O pin (Pxn).
Figure 24-8. 3-Port SDRAM configuration
When 4 EBI ports are available, SDRAM can be connected with 3-Port or 4-Port EBI configura-
tion. When 4-Port configuration is used, 8-bit data bus is available and all four chip selects will
be available.
