Host Bus 16-bit Muxed Interface
Figure 11-11 on page 873 shows how to connect the EPI signals to a 16-bit SRAM and a 16-bit Flash
memory with muxed address and memory using byte selects and dual chip selects with ALE. This
schematic is just an example of how to connect the signals; timing and loading have not been
analyzed. In addition, not all bypass capacitors are shown.
