BERL[n]
BER Receiver Lock[n]:
If BERL[n] is high, it indicates that BER Receiver of STi[n] is locked.
If BERL[n] is low, it indicates that BER Receiver of STi[n] is not locked.
Note: [n] denotes input stream from 16 - 31.

ST4_LIM
Stratum 4E Limits Select Bit
When this bit is high, the Stratum 4E limits are used for reference monitoring (i.e.
+/-64.713 ppm and +/-82.487 ppm over 10 seconds).When this bit is low, more relaxed
Relaxed Stratum 4E limits are used for reference monitoring (i.e. +/-240 ppm and
+/-250 ppm over 10 seconds). This is used in applications where a low quality clock
(+/-100 ppm) is used as a reference.

RFRE
Reference Frequency Register Enable
When this bit is low, the reference frequency value used in the DPLL comes from
appropriate reference frequency detector. When this bit is high, the reference frequency
value comes from Reference Frequency Register (RFR).
0
DPLL_
IRM
DPLL Internal Reset Mode
When this bit is low, the DPLL module is in the operational state. When this bit is high,
the DPLL module is in the power saving mode. Registers are not reset and are still
accessible in the power saving mode.
