SERDES A Common Transmit and Receive Channel Conguration Registers

—
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 transmit and
receive alarms of a
channel are pre-
vented from generat-
ing an interrupt. This
MASK bit overrides
the individual alarm
mask bits in the
Alarm Mask Regis-
ters. 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 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_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 transmit and
receive alarms of a
channel are pre-
vented from generat-
ing an interrupt. This
MASK bit overrides
the individual alarm
mask bits in the
Alarm Mask Regis-
ters. MASK = 1 on
device reset.
SWRST_AB
Transmit and Receive
Software Reset Bit,
Bank A, Channel B.
When SWRST = 1, this
bit provides the same

This is not a self-clear-

TESTEN_AB
Transmit and Receive Test

B. 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
