164 HSDI1_D3
I/O
HSDI port 1 data 3 pin. This signal is used as HSDI1_SACD_D3 for SACD transmit and receive.
165 HSDI1_D4
I/O
HSDI port 1 data 4 pin. This signal is used as HSDI1_SACD_D4 for SACD transmit and receive.
166 HSDI1_D5
I/O
HSDI port 1 data 5 pin. This signal is used as HSDI1_SACD_D5 for SACD transmit and receive.
167 HSDI1_D6
I/O
HSDI port 1 data 6 pin. This signal is used as HSDI1_SACD_D6 for SACD transmit and receive.
168 HSDI1_D7
I/O
HSDI port 1 data 7 pin. Data 0 is the most significant bit on the HSDI data bus.
157 HSDI1_DVALIDz
I/O
HSDI port 1 data valid pin. Programmable. Default active high.
This pin indicates if data on the HSDI data bus valid for reading or writing.
For transmit to 1394, this signal is provided by the system with the data.
For receive from 1394, iceLynx-Micro provides this signal with the data.
For HSDI DV modes, this signal is used as HSDI0_FrameSync indicating DV frame boundary.
If not used in transmit mode, this signal is pulled low.
154 HSDI1_ENz
I
HSDI port 1 enable. Programmable. Default active low. Input by the system to enable the HSDI for both
transmit to and receive from 1394.
If not used, this signal is pulled enabled (low or high depending on the polarity set). The application can
use HSDI_DVALID or HSDI_SYNC to validate the HSDI data.
156 HSDI1_SYNCz
I/O
HSDI port 1 sync signal. Programmable. Default active high.
This signal indicates the start of a packet.
For transmit to 1394, this signal is provided by the system with the data.
For receive from 1394, iceLynx-Micro provides this signal with the data.
If not used in transmit mode, this signal is pulled low or high depending on the polarity.
This signal is used as HSDI1_SACD_FRAME for SACD transmit and receive.

MLPCM_A
I/O
Audio MLPCM interface ancillary data. Ancillary data is input/output using this pin. For DVD-Audio,
MLPCM_LRCLK determines if ancillary left or ancillary right data is present.
This signal also functions as FLWCTL_A in flow control mode
9
MLPCM_BCLK
I/O
Audio MLPCM interface bit clock.
Multiple functions:
• DVD audio BCK (I)
• DVD audio BCK (O)
• Flow control BCK (I/O)
MLPCM interface, HSDI1 audio port, and HSDI1 video port share IsoPathBuffer 1. Only one interface can
access the buffer at a time.
11
MLPCM_D0
I/O
Audio MLPCM interface D0. Contains channel 1 and channel 2 information. MLPCM_LRCLK determines
which channel is present.
This signal also functions as FLWCTL_D0 in flow control mode.
12
MLPCM_D1
I/O
Audio MLPCM interface D1. Contains channel 3 and channel 4 information. MLPCM_LRCLK determines
which channel is present.
This signal also functions as FLWCTL_D0 in flow control mode
13
MLPCM_D2
I/O
Audio MLPCM interface D2. Contains channel 5 and channel 6 information. MLPCM_LRCLK determines
which channel is present.
This signal also functions as FLWCTL_D0 in flow control mode
10
MLPCM_LRCLK
I/O
Audio MLPCM interface left-right clock.
Multiple functions: • DVD audio LRCLK (I)
• DVD audio LRCLK (O)
• Flow control LRCLK (I/O)
