The EZ-KIT Lite board has a flash memory device that can be used to store user
specific boot code. By configuring the boot mode switch (SW1) and by
programming the flash, the board can run as a stand-alone unit. For information
about using the flash, see section 3.5.
SPORT0 is interfaced with an audio Codec, allowing you to create audio signal
processing applications. SPORT0 is also attached to an off-board connector to
allow communication with other serial devices. For information about SPORT0,
see section 4.2.2.
Additionally, the EZ-KIT Lite board provides access to most of the DSP’s
peripheral ports. Access is provided in the form of uninstalled expansion
interface connectors. These DSP’s USB pins are brought to this connector, but
require additional circuitry to function as a USB port. The PCI bus of the DSP is
not available at any connector of the EZ-Kit Lite. For information about the
expansion interface, see section 4.2.3.
