To access the SRAM and flash memories, set up a Parallel Port DMA. For
more information on how to connect the SRAM and flash memories, see
"Parallel Port" on page
The SPI flash memory connects to the SPI port of the processor and uses
as a chip select. In order for

An example program is included in the EZ-KIT Lite installation directory
to demonstrate how the parallel port and SPI port can be configured to
access the memories.

Analog Audio

The AD1835A is a high-performance, single-chip codec featuring four ste-
reo digital-to-analog converters (DAC) for audio output and one stereo
analog-to-digital converters (ADC) for audio input. The codec can input
and output data with a sample rate of up to 96 kHz on all channels. A
192 kHz sample rate can be used with the one of the DAC channels.
The processor is interfaced with the AD1835A via the DAI port. The DAI
interface pins can be configured to transfer serial data from the AD1835A
codec in either Time-Division Multiplexed (TDM) or Two-Wire Inter-
face mode. For more information on how the AD1835A connects to the
DAI, see "DAI Interface" on page
