X31 X and Y Values.
Reserved. These bits must be written to their
reset default value (0x0).
X31 X Value. This register specifies the
minimum value the confidence counter in the
X
reach in order to transition to the verification
state from the acquisition state. The confidence
counter is incremented every time the local
scrambler samples match the received
samples, and decremented when they do not
(see standard I.432).
X31 Y Value. This register specifies the
minimum value the confidence counter in the
X
reach in order to transition to the synchronized
state from the verification state. The confidence
counter is incremented every time the local
scrambler samples match the received
samples, and decremented when they do not
(see standard I.432).
X31 Z Value.
Reserved. These bits must be written to their
reset default value (0000000000).
X31 Z Value. This register specifies the
maximum value the confidence counter in the
X
achieve. The confidence counter is
incremented every time the local scrambler
samples match the received samples, and
decremented when they do not (see standard
I.432).
