RGB_IP_SEL, Address 0xF1 [0]
For SCART input, R, G, and B signals can be input either on
AIN4, AIN5, and AIN6 or on AIN7, AIN8, and AIN9.
0 (default)—B is input on AIN4, R is input on AIN5, and G is
input on AIN6.
1—B is input on AIN7, R is input on AIN8, and G is input
on AIN9.
MANUAL INPUT MUXING
By accessing a set of manual override muxing registers, the
analog input muxes of the ADV7188 can be controlled directly.
This is referred to as manual input muxing. Manual input
muxing overrides other input muxing control bits, including
INSEL and SDM_SEL.
Manual muxing is activated by setting the ADC_SW_MAN_EN
bit. It only affects the analog switches in front of the ADCs.

Therefore, if the settings of INSEL and the manual input
muxing bits (ADC0_SW/ADC1_SW/ADC2_SW/ADC3_SW)
contradict each other, the ADC0_SW/ADC1_SW/ADC2_SW/
ADC3_SW settings apply and INSEL and SDM_SEL are ignored.
Manual input muxing controls only the analog input muxes. For
the follow-on blocks to process video data in the correct format,
however, INSEL must still be used to indicate whether the input
signal is of YPbPr, Y/C, or CVBS format.
Restrictions in the channel routing are imposed by the analog
signal routing inside the IC; each input pin cannot be routed
to each ADC. Refer to Figure 6 for an overview on the routing cap-
abilities inside the chip. The four mux sections can be controlled by
the reserved control signal buses, ADC0_SW [3:0], ADC1_SW [3:0],
ADC2_SW [3:0], and ADC3_SW [3:0]. Table 11 explains the
control words used.
