8. SONY/PHILIPS DIGITAL
INTERFACE (S/PDIF)
The S/PDIF digital output is used to interface the
CS4205 to consumer audio equipment external to
the PC. This output provides an interface for stor-
ing digital audio data or playing digital audio data
to digital speakers. Figure 22 illustrates the circuits
necessary for implementing the IEC-958 optical or
consumer interface. For further information on
S/PDIF operation see application note AN22: Over-
view of Digital Audio Interface Data Structures [3].
For further information on S/PDIF recommended
transformers see application note AN134: AES and
S/PDIF Recommended Transformers [4].
9. EXCLUSIVE FUNCTIONS
Some of the digital pins on the CS4205 have mul-
tiplexed functionality. These functions are mutual-
ly exclusive and cannot be requested at the same
time. The following pairs of functions are mutually
exclusive:
GPIO and Serial Data Port (GPIO0 pin is
shared with LRCLK pin, GPIO1 pin is shared
with SDOUT pin, and GPIO[4:2] pins are
shared with SDI[3:1] pins)
EAPD and Serial Data Port Serial Clock
(EAPD pin is shared with SCLK pin)
S/PDIF and Second Serial Data Port (SPDO pin
is shared with SDO2 pin)
Use of the GPIO0/LRCLK, GPIO1/SDOUT, and
GPIO[4:2]/SDI[3:1] pins for serial data port has
priority over their GPIO functionality. There is no
priority assigned to the other two exclusive func-
tions. A function currently in use must be disabled
or powered down before the corresponding exclu-
sive function can be enabled. The following control
bits for these functions will behave differently than
normal bits: the EAPD bit in the Powerdown Con-
trol/Status Register (Index 26h), the GC[4:0] bits in
the SPEN bit in the S/PDIF Control Register (Index
68h), and the SDI[3:1], SDO2, and SDSC bits in
the Serial Port Control Register (Index 6Ah). These
bits can become read-only bits if they control a fea-
ture that is currently unavailable because the corre-
sponding exclusive feature is already in use, or the
corresponding master control for this feature is not
set.
