2.2 System LEDs
The C5515 eZdsp USB Stick has 5 Light Emitting Diodes (LED). These LEDs are under
the application software control running on the C5515 processor. These LEDs are shown in
the table below.
2.3 Switches
The C5515 eZdsp USB Stick has two push button switches. These switches can be read
by application software running on the C5515 processor. These switches are shown in the
table below.
2.4 Jumpers
The C5515 eZdsp stick has one jumper, JP1. When this jumper is shorted the C5515
eZdsp stick will be powered from the target USB interface, not the embedded USB
interface. When this jumper is shorted the embedded USB emulation and debug capability
are no longer available. This jumper is shipped in the “open” state from the factory.
