Preliminary specification
Universal Serial Bus (USB) Audio
Playback Recording Peripheral (APRP)
UDA1335H
After selecting an internal configuration map the user
cannot change the chosen settings for the GP pins,
internal configuration, descriptors etc.
The UDA1335H supports a maximum of two push-buttons
(six with I
2
C-bus expanders), which represent a certain
feature of the UDA1335H.
The UDA1335H supports a maximum of three outputs for
e.g. user LEDs.
For more information about the four configuration maps
located in the (E)PROM and the input and output functions
of the UDA1335H see the application documentation.
C
ONFIGURATION OPTIONS OF THE
UDA1335H
VIA AN
I
2
C-
BUS
EEPROM
At start-up, the UDA1335H will address I
2
C-bus slave
address 0
×
A0H and will check the first two byte locations
of the I
2
C-bus device with 0
×
55H and 0
×
AAH. If a match
occurs, the UDA1335H assumes that this I
2
C-bus device
is an EEPROM which is dedicated to the UDA1335H. It will
then read the configuration map stored in this EEPROM
instead of one of four configuration maps located in the
firmware of the microcontroller. The layout of the
configuration map is fixed, the values (except
bytes 0 and 1) are user definable. If the user wants to
change e.g. the manufacturer name this can be achieved
via the EEPROM code.
The communication between the UDA1335H and the
external I
2
C-bus device is based on the standard I
2
C-bus
protocol given in the Philips specification “The I
2
C-bus and
how to use it (including specifications)” which can be
ordered using the code 9398 393 40011. The I
2
C-bus has
two lines; a clock line SCL and a serial data line SDA
(see Fig.6).
