DPB_AUX_BUFFER_LOOPBACK_TEST_ENABLE: 
Project: All  
Default Value: 0b  
Enables test for the DPB-AUX I/O buffer. A 16 cycle clock pattern is output to the I/O 
buffer and compared against the looped back buffer output. The input clock is cdclk. 
With input clock at 512MHz the pattern will bea 1 MHz clock. It scales down with lower 
clock frequencies. The result is found in DP-AUX Buffer Loopback Test Result after DP-
AUX Buffer Loopback Test Done is set. Clear this bit to 0 after test is done to return DP-
AUX to normal operation. Loopback Test can be run simultaneously on all AUX buffers. 
Do not enable DP-AUX Buffer Loopback Test and DP-AUX Full Test simultaneously.
