—
PRBS_BA
Transmit and
Receive PRBS
Enable Bit,
Bank B, Chan-
nel A. When
PRBS = 1, the
PRBS genera-
tor on the trans-
mitter and the
PRBS checker
on the receiver
are enabled.
PRBS = 0 on
device reset.
MASK_BA
Transmit and Receive
Alarm Mask Bit, Bank
B, Channel A. When
MASK = 1, the trans-
mit and receive
alarms of a channel
are prevented from
generating an inter-
rupt. This MASK bit
overrides the individ-
ual alarm mask bits in
the Alarm Mask Reg-
isters. MASK = 1 on
device reset.
SWRST_BA
Transmit and Receive
Software Reset Bit,
Bank B, Channel A.
When SWRST = 1, this
bit provides the same
function as the hard-
ware reset, except all
conguration register
settings are preserved.
This is not a self-clear-
ing bit. Once set, this bit
must be cleared by writ-
ing a 0 to it. SWRST = 0
on device reset.

TESTEN_BA
Transmit and Receive Test
Enable Bit, Bank B, Channel A.
When TESTEN = 1, the trans-
mit and receive sections are
placed in test mode. TESTEN
= 0 on device reset. When the
global test enable bit GTES-
TEN = 0, the individual channel
test enable bits are used to
selectively place a channel in
test or normal mode. When
GTESTEN = 1, all channels are
set to test mode regardless of
their TESTEN setting.

PRBS_BB
Transmit and

Enable Bit,
Bank B, Chan-
nel B. When
PRBS = 1, the
PRBS genera-
tor on the trans-
mitter and the
PRBS checker
on the receiver
are enabled.
PRBS = 0 on
device reset.
MASK_BB
Transmit and Receive
Alarm Mask Bit, Bank
B, Channel B. When
MASK = 1, the trans-
mit and receive
alarms of a channel
are prevented from
generating an inter-
rupt. This MASK bit
overrides the individ-
ual alarm mask bits in

isters. MASK = 1 on
device reset.

This is not a self-clear-

are enabled.
PRBS = 0 on
