4.3.6.1. PIO Handshake Lines
PCS
The PIO chip select PCS must be set to ‘0’ to activate
the PIO in operation mode.
IN
PR
Pin PR
must be set to ‘1’ to validate data output from
MAS 35x9F PIO pins.
IN
PRTR
Ready to read. This signal indicates that the
MAS 35x9F is able to receive data in PIO input mode.
OUT
PRTW
Ready to write. This pin indicates that MAS 35x9F has
data available for PIO output mode.
OUT
EOD
EOD indicates the end of an DMA cycle in the IC’s PIO
input mode. In ’serial’ input mode it is used as Demand
signal, that indicates that new input data are required.
OUT
4.3.7. Serial Input Interface (SDI)
SID
SII
SIC
I
2
S compatible serial interface A for digital audio data.
In the standard firmware this interface is not used.
Note: Please refer to Bit [0] of Table 3–5

4.3.8. Serial Input Interface B (SDIB)
SIBD
SIBI
SIBC
The serial interface B is primarily used as bitstream
input interface. The SIBI line must be connected to
VSS in the standard application.

4.3.9. Serial Output Interface (SDO)
SOD
SOI
SOC
Data, Frame Indication, and Clock line of the serial
output interface. The SOI is reconfigurable and can be
adapted to several I

4.3.10. S/PDIF Input Interface
SPDI1
SPDI2
SPDIR
SPDIF1 and SPDIF2 are alternative input pins for
S/PDIF sources according to the IEC 958 consumer
IN
IN
IN
specification are used in conjunction with download
software only. A switch at D0:ff6 selects one of these
pins at a time. The SPDIR pin is a common reference
for both input lines (see Fig. 5–1 on page 89).
4.3.11. S/PDIF Output Interface
SPDO
The SPDO pin provides an digital output with standard
CMOS level that is compliant to the IEC 958 consumer
specification.
OUT
4.3.12. Analog Input Interfaces
In the standard MPEG-decoding DSP firmware the
analog inputs are not used. However, they can be
selected as a source for the D/A converters
(set MIX ADC scale of the D/A Converter Source
Mixer, Register 00 06
hex
in Table 3–16).
MICIN
MICBI
The MICIN input may be directly used as electret
microphone input, which should be connected as
described in application information (see Fig. 5–1 on
page 89). The MICBI signal provides the supply volt-
age for these microphones.
IN
IN
INL
INR
INL and INR are analog line-in input lines. They are
connected to the embedded stereo A/D converter of
the MAS 35x9F. The sources should be AC-coupled.
The reference ground for these analog input pins is the
VREF pin.

IN
4.3.13. Analog Output Interfaces
OUTL
OUTR
OUTL and OUTR are left and right analog outputs, that
may be directly connected to the headphones as
described in the application information (see Fig. 5–1
on page 89).
OUT
OUT
FILTL
FILTR
Connection to input terminal of output amplifier.Can be
used to connect a capacitance from OUTL respectively
OUTR to FILTL respectively FILTR in parallel to feed-
back resistor and thus implement a low pass filter to
reduce the out-of-band noise of the DAC.
