SDRAM Configuration
Multiplexing Data with Address Byte 0 and 1
When the data byte and address byte 0 (AD[7:0]), and address byte 1 (A[15:8]) are multiplexed,
they are output from the same port, and the ALE1 and ALE2 signal from the device control the
external address latches.
Figure 24-7. Multiplexed SRAM LPC connection using ALE1 and ALE2
Chip Select 3 on the EBI can be configured from SDRAM operation, and the EBI must be config-
ured for 3-Port or 4-Port interface. The SDRAM can be configured for 4-bit or 8-bit data bus, and
4-Port interface must be used for 8-bit data bus. The SDRAM interface signals from the EBI to
the SDRAM is listed in
Table 24-2.
