RFS = 1: Transfer

anomalies

from

second

section to first section and viceversa

allowed.

RFS = 0: Transfer

anomalies

from

second

section to first section and viceversa

not allowed.

LFS Local febe select.

Please report to the figure 10. LFS is useful in

repetor application to transfert or not the crc

anomalies (nebe) of a line section to the febe bit

of the same line section.

RFS = 0: The computed febe takes in to account

the local nebe.

RFS = 1: The computed febe does not take in to

account the local nebe.

Configuration Register 7 CR7

After reset: 02H

LOCK

PL2EN

DECT

DECT = 0: Normal mode

DECT = 1: DECT mode

PL2EN

PL2EN = 0: PLL2 remains frozen

PL2EN = 1: PLL2 tracks the phase of the receive

signal.

LOCK

LOCK = 0: no phase relation betweenSFSr and FSa

LOCK = 1: The phase of SFSr and FSa rising edges

is fixed

Configuration register TXB1

Significant only when format 3 selected.

(

µW/DSI Only)

After reset: 00H Time slot 0 selected.

B1X5 B1X4 B1X3 B1X2 B1X1 B1X0

B1X5-B1X0 Transmit B1 Time Slot Assignment

Those bits define the binary number of the trans-

mit B1 channel time-slot on Bx input. Time slot

are numbered from 0 to 63. The register content

is taken into account at each frame beginning.

Configuration register RXB1

Significant only when format 3 selected.

B1R5 B2R4 B2R3 B2R2 B2R1 B2R0

B1R5-B1R0 Receive B1 Time Slot Assignment

B1R5-B1R0 bits define the binary number of the

receive B1 channel time-slot on BR output. Time

slot are numbered from 0 to 63. The register con-

tent is taken into account at each frame begin-

ning.

Configuration register TXB2

Significant only when format 3 selected.

(

µW/DSI Only)

After reset: 01H Time slot 1 selected.

B2X5 B2X4 B2X3 B2X2 B2X1 B2X0

B2X5-B2X0 Transmit B2 Time Slot Assignment

Those bits define the binary number of the trans-

mit B2 channel time-slot on Bx input. Time slots

are numbered from 0 to 63. The register content

is taken into account at each frame beginning.

Configuration register RXB2

Significant only when format 3 selected. (

Only)

After reset: 01H Time slot 1 selected.

B2R5 B2R4 B2R3 B2R2 B2R1 B2R0

B2R5-B2R0 Receive B2 Time Slot Assignment

Those bits define the binary number of the receive

B2 channel time-slot on BR output. Time slot are

numbered from 0 to 63. The register content is

taken into account at each frame beginning.

Configuration register TXD

Significant only when format 3 is selected with the

D channel selected in the multiplexed mode.

After reset:

µW mode 08H (sub time slot 0, time slot 2 se-

lected)

SX0

DX5-SX0 Transmit D channel Time Slot Assign-

ment

DX5-DX0 and SX1-SX0 bits define the binary

number of the transmit D channel time-slot. DX5-

DX0 bits define the binary number of the 8 bits

wide timeslot. Time slot are numbered from 0 to

63. Within this selected time slot, SX1,SX0 bits

define the binary number of the 2 bits wide time-

slot. Sub time-slots are numbered 0 to 3. The reg-

ister content is taken into account at each frame

beginning.

Configuration register RXD

Significant only when format 3 is selected with the

D channel selected in multiplexed mode.

After reset:
