Indirect Register 00H: RHPP Pointer Interpreter Configuration
The SS bits enable (SSEN) bit selects whether or not the SS bits are taken into account in the
pointer interpreter state machine. When SSEN is set to logic 1, the SS bits must be set to 10 for a
valid NORM_POINT, NDF_ENABLE, INC_IND, DEC_IND or NEW_POINT indication. When
SSEN is set to logic 0, the SS bits are ignored.

The “justification more than 3 frames ago disable” (JUST3DIS) bit selects whether or not the
NDF_ENABLE, INC_IND or DEC_IND pointer justifications must be more than 3 frames
apart to be considered valid. When JUST3DIS is set to logic 0, the previous NDF_ENABLE,
INC_IND or DEC_IND indication must be more than 3 frames ago or the present
NDF_ENABLE, INC_IND or DEC_IND indication is considered an INV_POINT indication.
When JUST3DIS is set to logic 1, NDF_ENABLE, INC_IND or DEC_IND indication can be
every frame.
The relay path AIS (RELAYPAIS) bit selects the condition to enter the path AIS state in the
pointer interpreter state machine. When RELAYPAIS is set to logic 1, the path AIS state is
entered with 1 X AIS_ind indication. When RELAYPAIS is set to logic 0, the path AIS state
is entered with 3 X AIS_ind indications. This configuration bit also affects the concatenation
pointer interpreter state machine.
