Multiplexing Data with Address Byte 0
Figure 24-5. Multiplexed SRAM connection using ALE1 and ALE2
The Address Latch timing and parameter requirements are described in
277.
SRAM or external memory devices may have different timing requirements. To meet these vary-
ing requirements, each Chip Select can be configured with different wait-states. Timing details is
described in
The SRAM Low Pin Count (LPC) configuration enables EBI to be configured for multiplexing
modes where the data and address lines are multiplexed. Compared to SRAM configuration,
this can further reduce the number of pins required for the EBI. The available configurations is
shown in
Timing and Address Latch requirements is as for SRAM configuration.
When the data byte and address byte 0 (AD[7:0]) are multiplexed, they are output from the same
port, and the ALE1 signal from the device controls the address latch.
