Start-up and configuration of the UDA1331H
S
TART
-
UP OF THE
UDA1331H
After power-on, an internal power-on reset signal becomes
HIGH after a certain RC-time (R = 5 k
and C = C
ref
).
During 10 ms after power-on reset the UDA1331H has to
initiate the internal settings. After the power-on reset the
UDA1331H becomes master of the I
2
C-bus.
The UDA1331H tries to read the eventually connected
EEPROM and if an EEPROM is detected, the internal
descriptors are overwritten and the selected port
configuration is applied. If no EEPROM is detected, the
UDA1331H tries to read the logical levels of GP3 and GP0.
A choice can be made from four configuration maps via
these two pins.
C
ONFIGURATION SELECTION OF THE
UDA1331H
VIA A DIODE
MATRIX
The UDA1331H uses a configuration map to hold a
number of specific configurable data on hardware,
product, component and USB configuration level.
At start-up without EEPROM, the UDA1331H will scan the
logical levels of GP3 and GP0. With these two pins it is
possible to select one of the four possible (vendor specific)
configuration maps which are held in the external
(E)PROM. This selection can be achieved via a diode
matrix (see Fig.4).
After selecting a configuration map the user cannot
change the chosen settings for the GP pins, internal
configuration, descriptors, etc.
For more information about the four (vendor specific)
configuration maps located in the (E)PROM and the diode
matrix see the application documentation.
C
ONFIGURATION OPTIONS OF THE
UDA1331H
VIA AN
I
2
C-
BUS
EEPROM
If an EEPROM is detected (reading byte 0 as AAH and
byte 1 as 55H), the UDA1331H will use the configuration
map in the EEPROM instead of one of four configuration
maps. The layout of the configuration map is fixed, the
values (except bytes 0 and 1) are user definable
(see Table 6). If the user wants to change these values
(the manufacturers name for instance), this can be
achieved via the EEPROM code.
The communication between the UDA1331H 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.5).
