Programs can manage responses to signals by configuring registers. In a
sample audio application, for example, upon detection of a change of pro-
tocol, the output can be muted. This change of output and the resulting
behavior (causing the sound to be muted) results in an alert signal (an
interrupt) being introduced in response (if the detection of a protocol
change is a high priority interrupt).

Use of the

notice and respond to rising edges, falling edges, both rising and falling
edges, or neither rising nor falling edges so they can be masked separately.
Responses to changes in conditions of signals (including changes in DMA
state, introduction of error conditions, and so on) can only be enabled
using the
DAI_IRPTL_RE
Configuring Peripherals Using SRU1
The following sections describe how the various peripherals associated
with SRU1 are configured.
Configuring the SPORTs
The serial port chapter provides the signal sensitivity information of the
SPORT signals which needs to be considered while configuring the serial
ports using DAI pins.
