page 266. Table 24-1 on page 265 describes the SRAM interface signals.
Table 24-1. SRAM Interface signals.
24.5.1 No Multiplexing
When no multiplexing is used, there is a one-to-one connection between the EBI and the SRAM. No external address
latches are used.
Figure 24-3. Non-multiplexed SRAM connection.
24.5.2 Multiplexing address byte 0 and 1
When address byte 0 (A[7:0]) and address byte 1 (A[15:8]) are multiplexed, they are output from the same port, and the
ALE1 signal from the device controls the address latch.
