OSD Black Level Register (OSDBL)
Write address = 6CH, read address = ECH.
Read/write access: This register contains 4 factory-pre-
set bits [3:0] that must not be changed. Therefore,
when changing bit 4, first read this register, modify bit
4, and then write back the updated byte.
BIT
7–5
DEFAULT
000
FUNCTION
Don’t Care
OSD Image Black Level Control
This bit enables the alignment of the OSD image black level with the input image black level at
VOUT. Always enable this bit following power-on reset to ensure the correct OSD image brightness.
0 = Enable automatic OSD black level control
1 = Disable automatic OSD black level control
These bits are factory preset. To ensure proper operation of the MAX7456, do not change the
values of these bits.
xxxx = Factory preset—can be any one of the 16 possible values. This value is permanently stored in the MAX7456 and will always
be restored to the factory preset value following power-on reset or hardware reset.

Loss-of-Sync (LOS)
0 = Sync Active. Asserted after 32 consecutive input video lines.
1 = No Sync. Asserted after 32 consecutive missing input video lines.

0 = NTSC signal is not detected at VIN
1 = NTSC signal is detected at VIN

0 = PAL signal is not detected at VIN
1 = PAL signal is detected at VIN
NA = Not applicable.
X = Don’t care.
