After download or soft reset, and before
kickstarting the application (please see the Audio
Manager in the Application Messaging Section of
any Application Code User’s Guide for more
information on kickstarting), the host has the option
of changing the default hardware configuration.
Hardware configuration messages are used to
physically reconfigure the hardware of the audio
decoder, as in enabling or disabling address
checking for the serial communication port.
Hardware configuration messages are also used to
initialize the data type (i.e., PCM or compressed)
and format (e.g., I

S, left justified, etc.) for digital
data inputs, as well as the data format and clocking
options for the digital output port.
In general, the hardware configuration can only be
changed immediately after download or after soft
reset. However, some applications provide the
capability to change the input ports without
affecting other hardware configurations after
sending a special Application Restart message
(please see the Audio Manager in any Application
Code User’s Guide to determine whether the
Application
Section 11.4 at the end of this chapter will describe
how to construct a hardware configuration
message.
