Dai Interface - Analog Devices ADSP-21479 EZ-Board Manual

The input clock is 16.625 MHz. The default boot mode of the processor
is external parallel flash boot. See
page 2-10 for information on how to change the default boot mode.

DAI Interface

The digital application interface (DAI) pins are connected to the signal
routing unit (SRU) of the processor. The SRU is a flexible routing system
providing a large system of signal flows within the processor. The SRU
allows you to route the DAI pins to different internal peripherals in vari-
ous combinations.
The DAI connects various peripherals on the EZ-Board.
the DAI pin names, associated peripheral and net names, switch designa-
tors through which the pins are connected to the peripherals, and default
switch settings.
