INV_PRBS:
Sets the generator to invert the PRBS before inserting it in the payload. When set high, the
PRBS bytes will be inverted; else they will be inserted unmodified.
FORCE_ERR:
The Force Error bit is used to force bit errors in the inserted pattern. When set high, the MSB
of the next byte will be inverted, inducing a single bit error. The register will clear itself when
the operation is complete. A read operation will always result in a logic ‘0’.
B1E1_ENA:
This bit enables the replacement of the B1 byte in the SONET/SDH frame, by a
programmable value. The E1 byte is replaced by the complement of the same value. When
B1E1_ENA is high, the B1 and E1 bytes are replaced in the frame; otherwise they go through
the PRGM unaltered.
PRBS_SEQB:
This bit enables the insertion of a PRBS sequence or a sequential pattern in the payload.
When high, the payload is filled with PRBS bytes. When low, a sequential pattern is inserted.
