Clock (Output of ICA10)
Location: LCA1, RCA10

Horizontal sync (Output of ICA10)

Location: RCA9

Vertical sync (Output of ICA10)

Location: RCA8

4-2-5 DVI (Digital Visual Interface) signal

To process DVI signal, graphic card of AV device reads EDID data from ICI5(ROM). Then
DVI signal is directly inputted to ICD10, which output digital 24bit RGB and H/V. The output
goes through ICS1 for digital image processing
