Control B Registers
The Control B registers are read-write registers and
are shown in Table 8. The Control B registers select
device configuration and loopback control.
TAOS: Controls the transmission of all ones to the
line interface. A TAOS request overrides the data
transmitted to the line interface during local and re-
mote loopbacks.
RLOOP: Controls the remote loopback function for
the channel.
LLOOP1: Controls the local loopback #1 function
for the channel. Includes the jitter attenuator, if en-
abled. In host mode, selecting LLOOP1 and
LLOOP2 simultaneously causes all ones to be out-
put from RPOS/RNEG (RDATA).
LLOOP2: Controls the local loopback #2 function
for the channel. Includes the line driver, line receiv-
er, and jitter attenuator, if enabled. See LLOOP1,
above, for receive all ones function.
CON[3:0]: Controls the configuration of the line
driver, line receiver, coder, and driver tristate as
shown in the Transmitter section. Both channels
must be configured to operate at the same rate (both
T1 or both E1).
9.1.5
Arbitrary Waveform Registers
In addition to the predefined T1 and E1 pulse
shapes, arbitrary pulse shapes may be created dur-
ing Host mode operation using the registers shown
in Table 9. This flexibility can be used to compen-
