5.12.5 Insertion facilities
Two different values are inserted into the video signal: black level and coloured
background area. The black level insertion is done automatically in the SDA 9415. The
black level is inserted in the horizontal and vertical blanking period.
The second insertion facility produces a coloured background area on the display
controlled by the I²C Bus parameters YBORDERD, UBORDERD and VBORDERD.

Description
Y border value of display (Yborderd(3) Yborderd(2) Yborderd(1)
Yborderd(0) 0 0 0 0 = 00010000 = 16), YBORDERD defines the
4 MSB’s of a 8 bit value
U border value of display (Uborderd(3) Uborderd(2) Uborderd(1)
Uborderd(0) 0 0 0 0 = 10000000 = 128), UBORDERD defines the
4 MSB’s of a 8 bit value
V border value of display (Vborderd(3) Vborderd(2) Vborderd(1)
Vborderd(0) 0 0 0 0 = 10000000 = 128), VBORDERD defines the
4 MSB’s of a 8 bit value

5.12.6 Coarse delay
Before Digital-to-Analog conversion an adjustment of the phase of the luminance signal
can be performed (I²C Bus parameter COARSDEL, 5Ch). The delay of the luminance
can be varied by periods (-8, ...[1]... , +7) of the DAC clock (2*CLKD). This can be used
to compensate different delay times of external analog filters.
