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,
