Figure 5-1 EZ-KIT Lite System Block Diagram
The Enhanced Modular Analog Front End (EMAFE) connector is accessed through the
ADSP-21065L processor bus (16-bit parallel interface) and through two serial ports that
connect directly to the processor. One of these serial ports is shared with the on-board AD1819A.
