System Architecture
A detailed block diagram of the SHARC EZ-Extenderis shown in
Figure 2-1 . Note that the arrow in the bidirectional driver symbols
denotes the direction of the driver when in transmit mode. The bidirec-
tional driver is in transmit mode when the direction pin is pulled high.
Use the diagram in conjunction with information in
“DIP Switches and
Jumpers” on page 2-3 section of this manual to configure your SHARC
EZ-Extender.
Before using the SHARC EZ-Extender, familiarize yourself with the docu-
mentation and schematics of the target board and the ADSP-21262
EZ-KIT Lite. For example, on the EZ-KIT Lite, it may be necessary to
disable other devices on the parallel data access port (PDAP) or disable the
push buttons.
