5 DIGITAL APPLICATION
INTERFACE
The digital application interface (DAI) is comprised of a groups of periph-
erals and its respective signal routing unit (SRU). The inputs and outputs
of the peripherals are not directly connected to external pins. Rather, the
SRUs connect the peripherals to a set ofpins and to each other, based on a
set of configuration registers. This allows the peripherals to be intercon-
nected to suit a wide variety of systems. It also allows the ADSP-2136x
SHARC processors to include an arbitrary number and variety of periph-
erals while retaining high levels of compatibility without increasing pin
count.

Features

The DAI incorporates a set of peripherals and a very flexible routing (con-
nection) system permitting a large combination of signal flows as shown in

connectivity, and functionality variations possible. All routing related to
peripheral states for the DAI interface is specified using DAI registers. For
