Description
Arbitrary packet multiplex enable (1: Enabled)
Valid only when ARBITMODE is HIGH
Arbitrary packet mode selection

Arbitrary packet DID setting
Arbitrary packet SDID setting
Arbitrary packet DC setting
Field 1 multiplexing line
Field 2 multiplexing line
Arbitrary packet UDW setting
Description
Video input format (external pin/internal register)
configuration select. When set LOW, the video
input format is configured via the VM[3:0] pins.
When set HIGH, the video input format is
configured via the "VM[3:0]" bits.
Video signal detection flag. Set HIGH when 3
consecutive TRS are detected in the input video
signal.
To select this mode, set ARBITMODE bit 0 in Host Interface register 050h HIGH.
In this mode, the DID, SDID, DC and User Data Words must be programmed via
the corresponding Host Interface registers. Set the video line number for field 1 and
field 2 in which the arbitrary data packets are to be multiplexed using the
ARBITLINEA[11:0] and ARBITLINEB[11:0] Host Interface registers respectively.
The arbitrary data packet is multiplexed when ARBITON bit 1 in Host Interface
register 050h is set HIGH. ARBITON should be set LOW during the programming
of the arbitrary data packet in the Host Interface.
ARBITLINEA[11:0] and ARBITLINEB[11:0] should not be set to the two line
numbers following the line number set in the SW_LNA[12:0] and SW_LNB[12:0]
Host Interface registers. For example, with the default setting of line 7
ARBITLINEA[11:0] should not be set to line 8 or 9.
