The EZ-KIT Lite board has a total of 1 MB of parallel flash memory and
2 Mbit of SPI flash memory. The flash memories can store user-specific
boot code, allowing the board to run as a stand-alone unit. For more
information, see
and
Clock Ratio Select Switch (SW2)” on page 2-10
. The board has 16 MB of
SDRAM, which can be used at runtime or from which code can be
executed.
The DAI port of the processor connects to the AD1835A audio codec and
an external phase lock loop (PLL). The DAI interface facilitates develop-
ment of digital and analog audio signal-processing applications. See
The DPI port of the processor connects to the UART interface and the
SPI interface. The UART interface can connect to a standard RS-232 con-
nection, while the SPI connects to the 2 Mbit of serial flash memory.
Additionally, the EZ-KIT Lite board provides access to all of the proces-
sor’s peripheral ports. Access is provided in the form of a three-connector
expansion interface. See
“Expansion Interface” on page 2-7
for details.
