SERDES A Common Transmit and Receive Channel Configuration Registers
30004
PRBS_AA
Transmit and Receive
PRBS Enable Bit,
Bank A, Channel A.
When PRBS = 1, the
PRBS generator on
the transmitter and
the PRBS checker on
the receiver are
enabled. PRBS = 0
on device reset.
MASK_AA
Transmit and Receive
Alarm Mask Bit, Bank
A, 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_AA
Transmit and Receive
Software Reset Bit,
Bank A, Channel A.
When SWRST = 1,
this bit provides the
same function as the
hardware reset,
except all configura-
tion register settings
are preserved. This is
not a self-clearing bit.
Once set, this bit
must be cleared by
writing a 0 to it.
SWRST = 0 on
device reset.
SWRST_AB
Transmit and Receive
Software Reset Bit,
Bank A, Channel B.
When SWRST = 1,
this bit provides the
same function as the
hardware reset,
except all configura-
tion register settings
are preserved. This is
not a self-clearing bit.
Once set, this bit
must be cleared by
writing a 0 to it.
SWRST = 0 on
device reset.
SWRST_AC
Transmit and Receive
Software Reset Bit,
Bank A, Channel C.
When SWRST = 1,
this bit provides the
same function as the
hardware reset,
except all configura-
tion register settings
are preserved. This is
not a self-clearing bit.
Once set, this bit
must be cleared by
writing a 0 to it.
SWRST = 0 on
device reset.
SWRST_AD
Transmit and Receive
Software Reset Bit,
Bank A, Channel D.
When SWRST = 1,
this bit provides the
same function as the
hardware reset,
except all configura-
tion register settings
are preserved. This is
not a self-clearing bit.
Once set, this bit
must be cleared by
writing a 0 to it.
SWRST = 0 on
device reset.

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

PRBS_AB
Transmit and Receive
PRBS Enable Bit,
Bank A, Channel B.
When PRBS = 1, the
PRBS generator on
the transmitter and
the PRBS checker on
the receiver are
enabled. PRBS = 0
on device reset.
MASK_AB
Transmit and Receive
Alarm Mask Bit, Bank
A, 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
the Alarm Mask Reg-
isters. MASK = 1 on
device reset.

bit GTESTEN = 0, the indi-
vidual channel test enable
bits are used to selectively
