1.11.2 Arbitrary Data Multiplexing in Host Interface Mode
To select this mode, set ARBITMODE bit 0 in Host Interface
register 050h HIGH. In this mode, the DID, SDID, DC and

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]

DESCRIPTION
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
field 1, ARBITLINEA[11:0] should not be set to line 8 or 9.
