Figure 44.

 

DVI-D Interface 

 
One of the main changes in the DSS area on the –xM is the change of the DSS pin usage. 
The processor requires that different pins be used if 720p resolutions are required. These 
pins are different than those that are currently used on the BeagleBoard. The basic change 
requires  that  the 

DSS_D0-D5

  need  to  be  moved  to  the  pins  that  normally  carry  the 

DSS_D18-D23

  leads.  In  this  case,  the  signals  for 

DSS_D18-D23

  need  to  be  moved  to 

other pins. Reflected in 

Figure 44

 are four resistor packs inside either Red or Blue boxes. 

These  are  the  loading  options  to  enable  the  new  mode  used  by  the  –xM  or  the  legacy 
mode used by the BeagleBoard. The resistor packs in the RED boxes are installed and the 
BLUE boxes are not installed on the –xM to support the 720p resolution.  
 
For legacy operation, you would need to install the BLUE boxes and leave out the RED 
boxes. The SW will take care of this automatically, but you may want to do this if your 
design were to need to work in the legacy mode.
