The EZ-KIT Lite board has a total of 1 MB of parallel flash memory and
2M bit of SPI flash memory. Flash memories can store user-specific boot
code and allow the board to run as a standalone unit. For more informa-
tion, see "External Memory" on page 1-12

SDRAM, which can be used at runtime or from which code can be
executed.
The DAI port of the processor is connected to the AD1835A audio codec
and an external phase lock loop (PLL). The DAI interface facilitates devel-
opment of digital and analog audio signal-processing applications. See
"Analog Audio" on page 1-14
The DPI port of the processor is connected to the UART and SPI inter-
faces. The UART interface can connect to a standard RS-232, while the
SPI connects to the 2M bit 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
