8.7.2
In static pin mode the pins DEEM0 and DEEM1 control the
de-emphasis mode; see Table 3.
Table 3 De-emphasis control
8.7.3
In static pin mode the digital audio interface formats can be
selected via pin 17 (SF1) and 19 (SF0). The following
interface formats can be selected (see also Table 4):
Table 4 Input format selection in the static mode
It should be noted that the digital audio interface holds that
the BCK frequency can be 64 times the WS maximum
frequency, or f

8.8
The device is set to L3 mode by setting the STATIC pin to
LOW. The device can then be controlled via the L3
microcontroller interface (see Chapter 9).
8.8.1
The following interface formats can be selected in the
L3 mode:
8.8.2
The UDA1328 can be addressed via the L3 microcontroller
interface using one of two addresses. This is done in order
to individually control the UDA1328 and other Philips
DACs or CODECs via the same L3 bus.
The address can be selected using pin 25 (DEEM0) in
L3 mode. When pin 25 is set LOW, the address is 000100.
When pin 25 is set HIGH the address is 000101.
