The EZ-KIT Lite board has a total of 1 MB of parallel flash memory and
2 Mbit of SPI flash memory. Flash memories can store user-specific boot
code and allow the board to run as a stand-alone unit. For more informa-
tion, see “External Memory” on page 1-7 and “Boot Mode and Clock
Ratio Select Switch (SW2)” on page 2-10. The board also has 512 KB of
SRAM and 16 MB of SDRAM, which can be used at runtime.
The DAI port of the processor is connected to the AD1835A audio codec,
Sony/Philips Digital Interface (S/PDIF), and an external phase lock loop
(PLL). The DAI interface facilitates development of digital and analog
audio signal-processing applications. See “Analog Audio” on page 1-10
and “S/PDIF Coax Connectors (J7 and J8)” on page 2-24 for more
information.
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 connector,
while the SPI connects to 2 Mbit of serial flash memory.
