Signal Descriptions
8.12 Digital Audio Interface Signals
8.13 Subcode Interface
There is a 3-line subcode interface on the SCF5249. This 3-line subcode interface allows the device to
format and transmit subcode in EIAJ format to a CD channel encoder device. The three signals are
described in

Table
Serial Module Signal
The EBUOUT2 signal is only used on the 160 MAPBGA package.
The SUBR, SFSY, and the RCK signals are only used in the 160 MAPBGA
package.

Table 11. Subcode Interface Signal
The EBUIN1/GPI36, EBUIN2/GPI37, EBUIN3/ADIN0/GPI38, and
EBUIN4/ADIN1/GPI39 multiplexed signals can serve as general
purpose input or can be driven by various digital audio (IEC958) input
sources. Both functionalities are always active. Input chosen for
IEC958 receiver is programmed within the audio module. Input value
on the 4 pins can always be read from the appropriate gpio register..
The EBUOUT1_GPO36 and EBUOUT2_GPO37 multiplexed pins can
serve as general purpose I/O or as digital audio (IEC958) output.
EBUOUT1 is digital audio out for consumer mode, EBUOUT2 is digital
audio out for professional mode. The functionality of the pins is
programmed with the GPIO-FUNCTION and GPIO1-FUNCTION
register. During reset, the pin is configured as a digital audio output.
Subcode clock input. When pin is used as subcode clock, this pin is
driven by the CD channel encoder.
Subcode sync output
This signal is driven high if a subcode sync needs to be inserted in the
EFM stream.
Subcode data output
This signal is a subcode data out pin.
