p26 = n, where ’n’ = ‘0’ (DVB) or ‘1’ (530)
Note: If in 530 mode, the Interface Clock Mode (p27) shall
be set to Serial Clock.
p27 = n, where ‘n’ = ‘0’ (Serial) or ‘1’ (Parallel)
p28 = n, where ‘n’ = ’0’ (Normal) or ‘1’ (Invert)
p29 = n, where ‘n’ is ‘0’ (Normal) or ‘1’ (Invert).
p26 = n, where ‘n’ = ‘0’ (Serial) or ‘1’ (Parallel)
Note: ASI/RS-422 Incompatible Modes:
1. Interface Select Mode (p26) = ASI
and Clock (15) INVERTED.
2. Interface Select Mode (p26) = ASI
and Data (16) INVERTED.
p26 = n, where ‘n’ is ‘0’ or ‘1’
(0 = DVB, 1 = 530 for RS-422 Interface)
(0 = ASI, 1 = RS-422 for ASI/RS-422 Interface)
(0 = ASI, 1 = LVDS for ASI/LVDS Interface)
p27 = n, where ‘n’ is ‘0’ (Normal) or ‘1’ (Invert)

p29= n, where ‘n’ is ‘0’ (Normal) or ‘1’ (Invert)
p30 = n, where ‘n’ is ‘0’ (Off) or ‘1’ (On)
Note: ASI/LVDS Incompatible Modes:
1. Interface Select Mode (p26) = ASI
