Manual Input Muxing
By accessing a set of manual override muxing registers, the
analog input muxes of the ADV7189B can be controlled
directly. This is referred to as manual input muxing.
Manual input muxing overrides other input muxing control
bits, for example, INSEL. The manual muxing is activated by
setting the ADC_SW_MAN_EN bit. It only affects the analog
switches in front of the ADCs.
This means if the settings of INSEL and the manual input
muxing registers (ADC0/1/2_sw) contradict each other, the
ADC0/ADC1/ADC2_sw settings apply and INSEL is ignored.
Manual input muxing controls only the analog input muxes.
INSEL[3:0] still has to be set so the follow-on blocks process
the video data in the correct format.
This means INSEL must be used to tell the ADV7189B whether
the input signal is of component, YC, or CVBS format.
Restrictions in the channel routing are imposed by the analog
signal routing inside the IC; every input pin cannot be routed
to each ADC. Refer to
145H
Figure 6 for an overview on the routing
capabilities inside the chip. The three mux sections can be
controlled by the reserved control signal buses ADC0/ADC1/
ADC2_sw[3:0].
