:
Arbitrary data packet demultiplex. Valid only when
"ARBITMODE" is HIGH. When set HIGH, arbitrary
data packets will be demultiplexed from the Luma
video data stream. Must be set LOW again to
access valid data in the "ARBITUDW" registers.
Arbitrary packet mode select. When set HIGH,
arbitrary data packets are demultiplexed and the
User Data Words are stored in Host Interface
registers 100h to 1FEh. No data will be output on
the PKT[7:0] external pins and PTKTEN will be
LOW. When set LOW, arbitrary data packets are
demultiplexed and output at the PKT[7:0]
external pins.
Arbitrary packet Data ID setting. Designates the 8
LSBs of the DID word of the arbitrary data packet to
be demultiplexed. The 2 MSBs are internally
generated. "ARBITDID[7]" is the MSB and
"ARBITDID[0]" is the LSB. Valid only when
"ARBITMODE" is HIGH.
Arbitrary packet Secondary Data ID setting.
Designates the 8 LSBs of the secondary DID word
of the arbitrary data packet to be demultiplexed.
The 2 MSBs are internally generated.
"ARBITSDID[7]" is the MSB and "ARBITSDID[0]" is
the LSB. Valid only when "ARBITMODE" is HIGH.
Arbitrary packet DC setting. Designates the 8 LSBs
of the Data Count word of the arbitrary data packet
to be demultiplexed. The 2 MSBs are internally
generated. "ARBITDC[7]" is the MSB and
"ARBITDC[0]" is the LSB. Valid only when
"ARBITMODE" is HIGH.
Field 2 arbitrary packet demultiplex line number
setting. Designates the field 2 video line from which
the arbitrary data packets will be demultiplexed.
Valid only when "ARBITMODE" is HIGH.
Field 1 arbitrary packet demultiplex line number
setting. Designates the field 1 video line from which
the arbitrary data packets will be demultiplexed.
Valid only when "ARBITMODE" is HIGH.
Arbitrary packet User Data Word. Designates the 8
LSBs for up to 255 arbitrary packet User Data
Words. Arbitrary data can be read from these
registers once "ARBITON" has been set HIGH to
LOW. Valid only when "ARBITMODE" is HIGH.
