SAB9076H
SA 0AH TO SA 0CH ACQUISITION FINE POSITIONING
REGISTERS
These registers determine the start of the acquisition area.
Horizontal fine positioning can be adjusted with 16 steps of
2 pixels, vertical fine positioning can be adjusted with
256 steps of 1 line/field.
SA 0DH TO SA 0EH SELECTION REGISTERS
The MLSEL3 to MLSEL0 and SLSEL3 to SLSEL0 bits
control which PIP is live. Both main channel and
sub-channel can have one live PIP. Counting is carried out
from upper-left to lower-right.
The MBSEL3 to MBSEL0 and SBSEL3 to SBSEL0 bits
control which PIP border has a different colour. Both main
channel and sub-channel can have a different PIP channel
border selection. Counting is done from upper-left to
lower-right.
SA 0FH BORDER SIZE REGISTER
This register controls the border size. The minimum
horizontal border is 2 pixels. The minimum vertical border
is 1 line. The vertical border size is multiplied by the
FH mode number before it is displayed on the screen.
SA 10H AND SA 11H BORDER COLOUR AND BORDER SELECT
COLOUR OF SUB-CHANNEL REGISTERS (see Table 5)
If SBON is set to logic 1 then the border of the sub-channel
is visible. SBBRT and SBCOL control the brightness and
colour of the sub-channel border colour.
If SBSON is set to logic 1 then one sub-PIP border can
have a different colour. This border is selected by the
SBSEL3 to SBSEL0 bits.
The SBSBRT and SBSCOL bits control the brightness and
colour off the sub-border selection colour.
SA 12H AND SA 13H BORDER COLOUR AND BORDER
SELECTION COLOUR OF MAIN CHANNEL REGISTERS
(see Table 5)
If MBON is set to logic 1 then the border of the main
channel is visible.
The MBBRT and MBCOL bits control the brightness and
colour of the main-channel border colour.
If MBSON is set to logic 1 then one main PIP border can
have a different colour. This border is selected by the
MBSEL3 to MBSEL0 bits.
The MBSBRT and MBSCOL bits control the brightness
and colour off the main-border selection colour.
SA 14H BACKGROUND CONTROL REGISTER (see Table 5)
If BGON is set to logic 1 then the background is visible.
BGBRT and BGCOL registers control the brightness and
colour of the background colour.
