When written to a logical 1, this bit disables internal generation of the HEC field. When disabled,
the HEC field from the UTOPIA interface remains unchanged in the transmitted cell. When
written to a logical 0, HEC is internally calculated and inserted in the transmitted cell.
When written to a logical 1, this bit enables the Transmit HEC Coset. When written to a logical 0,
the HEC Coset is disabled.
When written to a logical 1, this bit enables the Transmit Cell Scrambler. When written to a
logical 0, the Transmit Cell Scrambler is disabled.
When written to a logical 1, this bit causes the ERRPAT register to be XORed with the calculated
HEC byte for one transmit cell. These bits are cleared automatically by internal circuitry after the
indicated error insertion has taken place. Clearing takes precedence over a simultaneous write
operation to this register.
This bit controls the polarity of the sync pulse in DSL mode. Set to 1 for active high and to 0 for
active low.
Reserved, write to a logical 0.
When written to a logical 1, this bit enables the Transmit DSS Scrambler. When written to a
logical 0, the Transmit DSS Scrambler is disabled.
When written to a logical 1, this bit enables the Receive DSS Scrambler. When written to a
logical 0, the Receive DSS Scrambler is disabled.
