Bits 2 to 1: Jitter Attenuator Bandwidth Select [1:0] (JABWS[1:0]).
These bits JABWS[1:0] select the jitter
attenuator bandwidth. See Table 5-14 for details.

Bit 0: Receive Hitless-Protection Mode Control (RHPMC).
This bit, when set while the OE pin is low, will force
all the receivers to turn off any internal impedance matching on RTIPn and RRINGn. This is used for hitless-
protection switching when the user would like a system requiring no external relays in the system.

Bits 7 to 5: Bit Error-Rate Transceiver Select [2:0] (BTS[2:0]).
These bits select the LIU that the BERT applies
to. This is only applicable if the BERTE bit is set.
Bit 0: Bit Error-Rate Tester Enable (BERTE).
When this bit is set, the BERT is enabled. The BERT is only active
for one transceiver at a time selected by BTS[2:0].

Bits 7 to 0: BPV Error Insertion Register n (BEIRn).
A 0-to-1 transition on this bit causes a single bipolar
violation (BPV) to be inserted into the transmit data stream channel n. This bit must be cleared and set again for a
subsequent error to be inserted.
