DCR_INTI:
This bit is set when a depth check error is detected. It is cleared when the register is read
(but may be set again immediately thereafter if a further depth check error report is pending).
LINK[3:0]:
The LINK[3:0] field is used to specify the LIU octant data stream associated with the FIFO
buffer in which the depth check error was detected. LINK[3:0] should only be looked at when
DCR_INTI is a ‘1’. Valid values for LINK[3:0] are from 1 to 8.
This register will contain the interrupt status even if the corresponding interrupt enable is not
set.
