This register contains error event control bits.
BLKBIPO:
When BLKBIPO is a logic one, path FEBE indications are generated on a
block basis. A single FEBE is transmitted if one or more path B3 error
indications are detected per frame. When BLKBIPO is a logic zero, the
transmitted FEBE indicates the number of B3 errors detected (between 0 and
8 errors per frame).
BLKBIP:
When BLKBIP is a logic one, B3 errors are reported and accumulated on a
block basis. A single B3 error is accumulated and reported to the TPOP if one
or more B3 errors are detected per frame. When BLKBIP is a logic zero, each
B3 error is accumulated and reported.
ENSS:
The ENSS bit controls whether the SS bits in the payload pointer are included
in the pointer interpreter state machine. When ENSS is a logic one, an
incorrect SS bit pattern causes the pointer interpreter to enter the LOP (loss
of pointer) state and prevents a new pointer indication. When ENSS is a logic
zero, the SS bits are ignored by the pointer interpreter.
SOS:
The SOS controls the spacing between consecutive pointer justification
events in the receive stream. When SOS is a logic one, the definition of
inc_ind and dec_ind indications includes the requirement that active offset
changes have occurred at least three frames ago. When SOS is a logic zero,
