DVI Data Channel 0 Outputs: These pins provide the DVI differential outputs for
data channel 0 (blue).
DVI Data Channel 1 Outputs: These pins provide the DVI differential outputs for
data channel 1 (green).
DVI Data Channel 2 Outputs: These pins provide the DVI differential outputs for
data channel 2 (red).
Hot Plug Detect (internal pull-down): This input pin determines whether the
DVI is connected to a DVI monitor. When terminated, the monitor is required to
apply a voltage greater than 2.4 volts. Changes on the status of this pin will be
relayed to the graphics controller via the P-OUT/TLDET* or GPIO (1)/TLDET* pin
pulling low.
DVO I2C Data: This signal is used as the I2C_DATA for a digital display (i.e. TV-
Out Encoder, TMDS transmitter). This signal is tri-stated during a hard reset.
DVI DDC Clock: This signal is used as the DDC clock for a digital display
connector (i.e. primary digital monitor). This signal is tri-stated during a hard
reset.
DVI Clock Outputs: These pins provide the differential clock outputs for the DVI
interface corresponding to data on TDC (0:2) outputs.
