Multiplexing address byte 0 and 2
Multiplexing address byte 0, 1and 2
Figure 24-3. Multiplexed SRAM connection using ALE1
When address byte 0 (A[7:0]) and address byte 2 (A[23:16) are multiplexed, they are output
from the same port, and the ALE2 signal from the device control the address latch.
Figure 24-4. Multiplexed SRAM connection using ALE2
When address byte 0 (A[7:0]), address byte 1 (A[15:8]) and address byte 2 (A[23:16] are multi-
plexed, they are output from the same port, and the ALE1 and ALE2 signal from the device
control the external address latches.
