(TOC)
TMFn is high if PRBS/ARB is detected in synchronization in the transmit path. During the synchronization, TMFn
goes low for a T1/E1 clock cycle if a PRBS/ARB error is detected. TMFn is low if PRBS/ARB is out of synchronization.
TMFn is high if AIS is detected in the transmit path and low if it is cleared. This indication corresponds to the SAIS_S
bit (b7, STAT1,...). Refer to Section 3.5.4 Alarm Indication Signal (AIS) Detection and Generation.
TMFn is high if transmit over current is detected and low if it is cleared. This indication corresponds to the TOC_S bit
(b4, STAT0,...). Refer to Section 3.3.5.1 Transmit Over Current Protection.
TMFn is high if LOS is detected in the transmit line side and low if it is cleared. This indication corresponds to the
TLOS_S bit (b2, STAT0,...). Refer to Section 3.5.3.3 Transmit LOS (TLOS).
TMFn goes high for a T1/E1 clock cycle if an EXZ is detected in the transmit path, otherwise it is low. Refer to
Section 3.5.2 Excessive Zeroes (EXZ) Detection
TMFn goes high for a T1/E1 clock cycle if a BPV/CV is detected in the transmit path, otherwise it is low. Refer to
Section 3.5.1 Bipolar Violation (BPV) / Code Violation (CV) Detection and BPV Insertion.
TMFn goes high for a T1/E1 clock cycle if an EXZ or a BPV/CV is detected in the transmit path, otherwise it is low.
TMFn is high if LOS is detected in the transmit system side and low if it is cleared. This indication corresponds to the
SLOS_S bit (b1, STAT0,...). Refer to Section 3.5.3.2 System LOS (SLOS).

SEXZ, SBPV, SEXZ + SBPV or SLOS, as selected by the
TMF_DEF[2:0] bits (b7~5, TCF1,...). However, the indication of SBPV,
SEXZ + SBPV and SLOS is disabled automatically in Transmit Single
Rail NRZ Format mode. Refer to Table-22 for details.
TMFn can indicate the status of PRBS/ARB, SAIS, TOC, TLOS,
