Auxiliary Control 1:
AUXCTRL1 (0x843A)
Horizontal Blank Position
H. Blank
Reserved
H Blnk
HBPOS[4:0]
HBPOS_EN
RSV
HBD
Bit 0
When this bit is a 0, the horizontal blanking input at pin 28 is gated to the video outputs to provide horizontal blanking.
When it is a 1, the horizontal blanking at the outputs is disabled.
Bit 1
Reserved.
Bit 2
When this bit is a 1, the position of the Horizontal Blanking pulse can be programmably varied relative to the horizontal
flyback in number of pixels. When this bit is a 0, which is by default, the horizontal blanking pulse position will not be
programmable.
Bits 7–3
These 5 bits determine the position of the Horizontal Blanking Pulse with respect to the horizontal flyback in number of
pixels.
Auxiliary Control 2:
AUXCTRL2 (0x843E)
Res'd
Clamp
Switch
OSD
VBlank

RSV
CLMP

OOR
VBL
RSV
Bits 1–0
Reserved and should be set to zero.
Bit 2
This is the Vertical Blanking register. When this bit is a 1, vertical blanking is gated to the video outputs. When set to a
0, the video outputs do not have vertical blanking.
Bit 3
This is the OSD override bit. This should be set to 0 for normal operation. When set to a 1, the video outputs are
disconnected and OSD only is displayed. This is useful for the OSD display of special conditions such as “No Signal”
and “Input Signal Out of Range”, to avoid seeing unsynchronized video.
Bit 4
Setting this bit will internally tie the clamp pin to the horizontal sync pin, and the clamp pin will not require an external
input signal.
Bit 5
This is the Clamp Polarity bit. When set to a 0, the LM1276 expects a positive going clamp pulse. When set to a 1, the
expected pulse is negative going.
Bits 7–6
Reserved and should be set to zero.
OSD Tone Transparency:
OSD TRANSP TONE (0x85C0)
Res'd
OSD TONE
RSV
OSDTONE[6:0]
Bits 6–0
These bits determine the transparency level of the OSD background.
Bit 7
Reserved and should be set to zero.
Center Frequency:
EMPHASIS_CENTF(0x85C1)
Center Frequency
Res'd
CENTF[3:0]
RSV
Bits 3–0
Reserved and should be set to zero.
Bits 7–4
These 4 bits control the Center Frequency adjustment of the Hi-Brite window video signal for enhancement.
