Description: This variable controls the insertion of various types of path pointer diagnostic bit patterns in the transmit stream. It is a bit map that is netmod specific. Under normal operation it should be set to:

1 None -- No diagnostics

2 FTPTR -- Controls the insertion of the pointer value contained in the Arbitrary Pointer Registers into the stream. This allows upstream payload mapping circuitry to continue functioning normally and a valid SPE to continue to be generated, although it is unlikely to be extraced by downstream circuitry which should be in a loss of pointer state. If FTPTR is on, the APTR[9:0] bits of the Arbitrary Pointer Registers are inserted into the H1 and H2 bytes of the stream. At least one corrupted pointer is guaranteed to be sent.
