Pin Name Pin No I/O Description
HSDI1_SYNC 156 I/O HSDI Port 1 Sync Signal. Programmable. Default active high.
This signal is used to indicate the start of packet
For transmit onto 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 can be tied low or high
depending on the polarity.
This signal can be used as HSDI1_SACD_FRAME for SACD
Transmit and Receive.
DVD-Audio Interface Pins
MLPCM_A 14 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
MLPCM_BCLK 9 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 buffer 1. Only one interface can access the buffer at a
time.
MLPCM_D0 11 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.
MLPCM_D1 12 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
MLPCM_D2 13 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
MLPCM_LRCLK 10 I/O Audio MLPCM Interface Left-Right Clock. Multiple functions:
DVD Audio LRCLK (I)
DVD Audio LRCLK (O)
Flow Control LRCLK (I/O)
