2 BLACKFIN/SHARC USB EZ-EXTENDER HARDWARE REFERENCE This chapter describes the hardware design of the Blackfin/SHARC USB EZ-Extender. The following topics are covered. • “System Architecture” on page 2-2 Describes the board configuration and explains how the board components interface with the processor and EZ-Board. • “Jumper Settings” on page 2-3 Describes the on-board configuration jumpers.
System Architecture System Architecture A block diagram of the Blackfin/SHARC USB EZ-Extender is shown in Figure 2-1. Figure 2-1.
Blackfin/SHARC USB EZ-Extender Hardware Reference Jumper Settings Before using the Blackfin/SHARC USB EZ-Extender, follow the setup procedure in “Blackfin/SHARC USB EZ-Extender Setup” on page 1-2. Figure 2-2 shows the locations of all jumper headers. A two-pin jumper can be placed on the respective jumper header for different functionality. The following sections describe all possible jumper settings and associated functionality. Figure 2-2.
Jumper Settings USB Chip Select Jumper (JP1) The USB chip select jumper (JP1) connects an AMS signal from the EZ-Board to the chip select input on the NET2272 controller. The AMS0– 3 signals are available. By default, the jumper is installed on pins 7 and 8, which connect AMS3 to the chip select signal. USB IRQ Jumper (JP2) The USB IRQ jumper (JP2) connects a general-purpose IO signal from the EZ-Board to the interrupt output on the NET2272 controller. The GPIO1–4 signals are available.
