CXD1856Q/R
4. Description of Functions
4-1. Host Interface Function
• The CXD1856Q/R operation is controlled by writing and reading registers. Write and read can also be
performed to an external DRAM via the registers. See the separately issued Register Manual for the
relationship between the registers and operation.
• The host interface operates while XHCS is low and does not operate while XHCS is high.
• The host interface operating mode can be set to 4-line serial or 8-bit parallel. The operating mode is selected
automatically at the end of the initial access after the hardware has been reset. (See the figure below.)
Registers are not accessed correctly until this selection has been determined, or in other words until the end
of the initial access after the hardware has been reset. Also, the HA3 to HA0 inputs should all be fixed low
during the operating mode selection access.

1) In serial mode, input data is fetched in sync with the rise of HRW (SCK). Output data is synchronized with
the fall of HRW.
2) The initial byte (byte0) of the input after XHCS changes to low is a command. This command determines
the subsequent byte processing. See the following page for a description of commands and processing.
3) Input data is processed in one byte units. Therefore, when the final data consists of a number of bits which
is less than one byte, this deficient data is not processed. Be sure to input data with a number of bits which
is an integer multiple of 8. Also, the 0x20, 0x60, 0xA0 and 0xE0 commands process data in two byte units,
so data which is an even multiple of 8 should be input when using these commands.

1) The "write read" column indicates whether that command writes data to or reads data from the registers.
2) Bytes marked with "Register No. + U/L byte select" specify the register to be accessed as well as whether
to access the upper or lower bytes of the register. The upper 7 bits specify the register No., and the
lowermost bit specifies the upper or lower bytes. When the lowermost bit is "0", the lower bytes are
selected, when "1", the upper bytes are selected.
3) Bytes marked with "Register No." specify the register to be accessed. The upper 7 bits specify the register
No., and the lowermost bit can be either "0" or "1".
4) The "Auto inc." column indicates the presence of the register No. auto increment function. For commands
without this function, the most recently input register No. is valid. For example, in case of the command
0x00, the register data input by the odd bytes is written to the register specified by the previous byte's input.
For the command 0x20, all subsequent data is written sequentially to the register specified by the 2nd input
byte.
5) For commands with the register No. auto increment function, the register specified by the 2nd input byte is
accessed first, and then access shifts to the register No. incremented by one each time the data for one
register (2 bytes) is read or written. For example, when using the command 0x60, if 0x08 is specified by the
2nd input byte, the 3rd and 4th input bytes are written to register 0x08, and the 5th and 6th input bytes are
written to register 0x09.
6) Bytes marked with "register data" are the data to be written to the registers during write commands.
– 19 –
CXD1856Q/R
7) When executing read commands, register data output starts from the 3rd output byte (bit 16). All earlier
output data is invalid data. Access shifts to a new register each time the output for one register (2 bytes) is
finished. For example, in case of the command 0x10, the byte data specified by the 2nd input byte is output
to the 3rd output byte, the other byte data in the same register is output to the 4th byte, and the byte data
specified by the 4th input byte is output to the 5th output byte.
8) The "first bit" column indicates whether LSB first or MSB first processing is performed for input or output of
the 2nd and subsequent bytes. This specification does not apply to the 1st byte (command). Commands
are normally LSB first. If LSB first is specified, processing is performed in the order where the initial bit in
each byte is LSB and the final bit is MSB. This order is reversed for MSB first. Note that for registers, bit 15
noted in the Register Manual is MSB and bit 0 is LSB.
4-2. DRAM Interface Function
• The applicable DRAMs are speed version 70 devices (RAS access time (Trac) of 70ns or less) with the fast
page mode function.
• When the total capacity of the external DRAM is 4 Mbits, use a 2CAS type DRAM with a configuration of 256
Kwords × 16 bits. When the total capacity is 8 Mbits, use two 2CAS type DRAMs with a configuration of 256
Kwords × 16 bits or 512 Kwords × 8 bits.
• Refresh is performed automatically using RAS-only-refresh. External control is not necessary.
• The DRAM is divided into the image frame memory, audio bit stream buffer, video bit stream buffer, user
data and on-memory register areas.
• The user data area can be used freely by the user, and CD-ROM decoded output can also be transferred to
this area. This area can be used to store video CD PSD, etc.
• The desired DRAM areas can be accessed from the control microcomputer via the registers.
4-3. CD-ROM Decoder Function
• CD signal processor LSI interface
The CD-ROM decoder has a CD signal processor LSI (CD-DSP) interface which directly interfaces the serial
data output from the CD-DSP. This interface supports a wide variety of input formats to enable connection
with general CD-DSP.
• CD-ROM data decoding (supports CD-ROM XA format mode2, form1 and form2)
CD-ROM data input from the CD-DSP supports CD-ROM XA format (mode2, form1 and form2).
• Input CD-ROM data is decoded by the CD-ROM decoder block. Also, the CD-DA signal input from the CD-
DSP can be output directly from the audio interface.
• The CD-ROM decoder has the following decoding and data transfer operating modes. The real-time
correction and write-only modes facilitate the loading of video CD PSD to the external DRAM, etc.
1) Auto transfer mode
The MPEG pack data within one sector of the video CD is automatically transferred to the system
decoder, where the audio stream sector or video stream sector can be decoded. This mode transfers
2324 bytes counted from the initial byte of user data within one sector to the system decoder.
2) Real-time correction mode
This mode executes error detection and correction processing for mode2, form1 sectors. The 2048 bytes
of user data within the error processed sector are transferred to the user area of the external DRAM. The
4 bytes of header information within the sector can also be loaded in the on-memory register within the
DRAM.
3) Write-only mode
This mode transfers the 2340 bytes of header, subheader and user data within one sector to the user area
of the external DRAM. When a form1 sector is input, error detection and correction processing is
performed and then the data is transferred to the buffer memory. When a form2 sector is input, the data is
transferred as is.

4-4. System Decoder Function
• The MPEG1 system layer (ISO/IEC 11172-1) is decoded, the audio and video bit streams are separated, and
each bit stream is transferred to the respective bit stream buffer.
• The MPEG1 bit stream input can be selected from either the built-in CD-ROM decoder or the host interface.
• The system decoder has a 128-word (256-byte) FIFO for the bit stream input.
• Audio and video sync playback are controlled according to the time stamp within the bit stream.
4-5. Video Decoder Function
• The MPEG1 video layer (ISO/IEC 11172-2) is decoded. This function supports the range where
constrained_parameter_flag = "1" and video CD high resolution still picture.
• Video CD high resolution still picture (NTSC, PAL) can be decoded with a single external 4-Mbit DRAM.
• Special decoding functions are as follows. Slow playback, fast forward and other modes can be realized by
combining these functions.
I-Play: Only I-Pictures are decoded.
Still (Pause): Decoding is paused.
1 Frame Play: Only one frame (picture) is decoded.
IP-Play: Only I and P-Pictures are decoded.
IPB-Play: Alternate frames of continuous B-Pictures and all I and P-Pictures are decoded.
• This function supports digest play.
• The various information in the bit stream is loaded to the on-memory register area within the external DRAM.
4-6. Video Post Processor and Sync Generator Functions
• The image data output format can be selected from 24-bit RGB, 24-bit YCbCr and 16-bit YCbCr. See the
following page.
• Fade in and fade out are allowed.
• Image enlargement and reduction are allowed.
• The CXD1856Q/R contains an OSD color table and selector, and OSD display is achieved by inputting the
OSD character signal.
• The video sync signal can be generated using the built-in sync generator. Image data can also be output in
sync with an externally input video sync signal.

CXD1856Q/R
4-7. Audio Decoder Function
• MPEG audio stream decoding is performed for MPEG1 standard (ISO/IEC 11172-3) layer 1 and layer 2.
• Monaural, dual, stereo and joint stereo decoding modes are supported.
• All MPEG1 standard sampling frequencies (32kHz, 44.1kHz, 48kHz) are supported.
• All MPEG1 standard bit rates are supported.
Layer 1: 32Kbps (monaural/stereo) to 448Kbps (monaural/stereo)
Layer 2: 32Kbps (monaural) to 384Kbps (stereo)
• The audio decoder's audio interface output port is equipped with a PCM audio output which outputs decoded
audio data in bit serial format and a digital audio interface output (digital out). The audio interface is set by
setting the internal registers.
1) LRCK and BCK generation
The LR clock and bit clock can be generated by frequency dividing the clock input from external pins XTLI
or FSXI. The generated clocks are output from the BCKO and LRCO pins, respectively. LRCO and BCKO
can be output in the desired polarity. Also, the number of slots per sample supports the three types of 32,
48 and 64 bit clocks/LRCK.
2) PCM audio output format
The PCM audio output format can be set to any of the following combinations to allow connection with a
wide range of 1-bit D/A converters.
16-bit word length, MSB first or LSB first, frontward truncation or rearward truncation
18-bit word length, MSB first or LSB first, frontward truncation or rearward truncation
20-bit word length, MSB first or LSB first, frontward truncation or rearward truncation
24-bit word length, MSB first or LSB first, frontward truncation or rearward truncation
3) Digital out format
The digital out output format supports the type2, form1 format for consumer use. The output word length
can be selected from 16, 18, 20 or 24 bits.
4) Decoded channel assignment
Channels 1 and 0 of the audio sample obtained by decoding the MPEG audio stream can be assigned to
the L and R channel outputs in any combination.
5) Audio mute
The audio output contains a zero-cross mute circuit. Zero-cross detection is performed for 44 sample
sections (approximately 0.1ms when fs = 44.1kHz), and if zero-cross is not detected, the output is forcibly
muted.
6) Attenuator
The audio output contains an attenuator circuit. Attenuation of –12dB can be obtained by setting the
internal register.
7) CD-DA output mode
When playing back a CD-DA disc, the data input from the CD-DSP can be output directly from the PCM
audio output (DATO) and the digital audio interface output port (DOUT). Output ports LRCO and BCKO can
also select and output the clock inputs LRCI and BCKI from the CD-DSP.
