Diag_PosJust :
The Diag_PosJust bit forces the SVCA to generate outgoing positive justification event.
When set to 1, the SVCA generates positive justification events at the rate of one every four
frames regardless of the current level of the internal fifo. Prolonged application may cause
the FIFO to overflow.
Note : Diag_PosJust and Diag_NegJust must not be set to one at the same time. If that
occurs, their operation is disabled.
Diag_NegJust :
The Diag_NegJust bit forces the SVCA to generate outgoing negative justification events.
When set to 1, the SVCA generates negative justification events at the rate of one every four
frames regardless of the current level of the internal fifo. Prolonged application may cause
the FIFO to underflow.
Note : Diag_PosJust and Diag_NegJust must not be set to one at the same time. If that
occurs, their operation is disabled.
Diag_LOP :
When set high, the Diag_LOP bit forces the SVCA to invert the outgoing NDF field of the
payload (selected path(s)) pointer causing downstream pointer processing elements to enter
a loss of pointer (LOP) state.
