Type
DVI Data Channel 0 Outputs: These pins provide the DVI differential
O
outputs for data channel 0 (blue).
DVI Data Channel 1 Outputs: These pins provide the DVI differential
O
outputs for data channel 1 (green).
DVI Data Channel 2 Outputs: These pins provide the DVI differential
O
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,
I
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
I/O
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
I/O
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
O
for the DVI interface corresponding to data on TDC (0:2) outputs.
