INDICATION
3.5.7.1 RMFn Indication
used as RMFn. In Receive Dual Rail Sliced mode, the RCLKn/RMFn pin
is used as RMFn. Refer to Table-3 Multiplex Pin Used in Receive

RMFn is high if PRBS/ARB is detected in synchronization in the receive path. During the synchronization, RMFn goes
low for a T1/E1 clock cycle if a PRBS/ARB error is detected. RMFn is low if PRBS/ARB is out of synchronization.
Refer to Section 3.5.5 PRBS, QRSS, ARB and IB Pattern Generation and Detection.
RMFn is high if AIS is detected in the receive path and low if it is cleared. This indication corresponds to the LAIS_S
bit (b6, STAT1,...). Refer to Section 3.5.4 Alarm Indication Signal (AIS) Detection and Generation.
RMFn outputs XOR data of positive and negative sliced data.
RMFn goes high for a T1/E1 clock cycle if an EXZ is detected in the receive path, otherwise it is low. Refer to
Section 3.5.2 Excessive Zeroes (EXZ) Detection.
RMFn goes high for a T1/E1 clock cycle if a BPV/CV is detected in the receive path, otherwise it is low. Refer to
Section 3.5.1 Bipolar Violation (BPV) / Code Violation (CV) Detection and BPV Insertion.
RMFn goes high for a T1/E1 clock cycle if an EXZ or a BPV/CV is detected in the receive path, otherwise it is low.
RMFn is high if LOS is detected in the receive path and low if it is cleared. This indication corresponds to the LLOS_S
bit (b0, STAT0,...). Refer to Section 3.5.3.1 Line LOS (LLOS).

LEXZ + LBPV, LLOS, output recovered clock (RCLK) or XOR output of
positive and negative sliced data, as selected by the RMF_DEF[2:0] bits
(b7~5, RCF1,...). Refer to Table-21 for details.
RMFn can indicate the status of PRBS/ARB, LAIS, LEXZ, LBPV,
