Auxiliary Blanking Input: In a typical system, this pin is connected to the RGB status pin
(pin 16) from the auxiliary SCART connector.
Auxiliary Red Input: In a typical system, this pin is connected to the RED input pin (pin
15) of the auxiliary SCART connector. This input can be selected as the signal source
for the
TV_R
output pin.
Auxiliary Green Input: In a typical system, this pin is connected to the GREEN input pin
(pin 11) of the auxiliary SCART connector. This input can be selected as the signal
source for the
TV_G
output pin.
Auxiliary Blue Input: In a typical system, this pin is connected to the BLUE input pin (pin
7) of the auxiliary SCART connector. This input can be selected as the signal source for
the
TV_B
output pin.
Auxiliary Function Pin: This is a bi-directional pin. As an input, it digitizes the analog
voltage on the auxiliary SCART function pin. As an output, it puts out one of three
voltage levels to the auxiliary SCART function pin.
Auxiliary Chroma Input: In a typical application, this pin is AC coupled to the Red input
line from the Auxiliary SCART connector. When the SVHS mode is selected from the
Auxiliary SCART video source, this pin is internally summed to the
Aux_YC
input to
generated a composite video signal for the
Mod_YC
output.
Auxiliary Video Input: In a typical system, this pin is connected to the composite video
input pin (pin 20) of the auxiliary SCART connector. This input can be selected as the
signal source for the
TV_YCout
.
Auxiliary Left Audio Input: In a typical system, this pin is connected to the L Audio
Output pin (pin 3) of the auxiliary SCART connector. This input can be selected as the
signal source for the
TV_Lout
.
Auxiliary Right Audio Input: In a typical system, this pin is connected to the R Audio
Output pin (pin 1) of the auxiliary SCART connector. This input can be selected as the
signal source for the
TV_Rout
.
Encoder Blanking Input: In a typical system, this pin is connected to the blanking signal
from the external video encoder device.
Encoder Red Input: In a typical system, this pin is connected to the RED output pin from
the external video encoder device. This input can be selected as the signal source for
the
TV_R
output pin.
Encoder Green Input: In a typical system, this pin is connected to the GREEN output pin
from the external video encoder device. This input can be selected as the signal source
for the
TV_G
output pin.
Encoder Blue Input: In a typical system, this pin is connected to the BLUE output pin
from the external video encoder device. This input can be selected as the signal source
for the
TV_B
output pin.
