The EZ-KIT Lite contains three types of memory: parallel flash (1 MB),
SPI flash (2M bit), and SDRAM (128M bit). Flash memories can store
user-specific boot code and allow the board to run as a standalone unit.
For information on how to select a boot device for the processor, see
"Boot Mode and Clock Ratio Select Switch (SW2)" on page
Table 1-1 provides start and end addresses of the on-board external
memories.

Parallel flash memory and SDRAM are connected to the external memory
of the processor.
SDRAM memory is connected to the SDRAM controller of the processor.
A set of programmable timing parameters is available to configure the
SDRAM banks to support slower memory accesses. Care must be taken
when configuring the SDRAM control registers. For more information
regarding the SDRAM controller setup, refer to the ADSP-2137x SHARC
Processor Hardware Reference.
An example program is included in the EZ-KIT Lite installation directory
to demonstrate the controller setup.
