The EZ-KIT Lite board has a total of 1 MB of parallel Flash memory and
512 Kbit of SPI Flash memory. The Flash memories can store user-spe-
cific boot code, allowing the board to run as a stand-alone unit. For more
information, see
“Using External Memory” on page 2-2
and
“Boot Mode
and Clock Ratio Select Switch (SW10)” on page 3-11
. The board also has
512 KB of SRAM, which can be used at runtime.
The DAI of the DSP connects to the AD1835A audio codec and the
CS8416 SPDIF receiver. These devices allow you to create digital and ana-
log audio signal processing applications. See
“Using Analog Audio” on
page 2-3
and
“Using Digital Audio” on page 2-5
for more information.
