RXHR_AA
Receive Half Rate
Selection Bit, Bank
A, Channel A. When
RXHR = 1, the
RBC[1:0] clocks are
issued at half the
scheduled rate of the
reference clock.
RXHR = 0 on device
reset.
PWRDNR_AA
Receiver Power
Down Control Bit,
Bank A, Channel A.
When PWRDNR =
1, sections of the
receive hardware
are powered down to
conserve power.
PWRDNR = 0 on
device reset.
SDOVRIDE_AA
Receive Signal
Detect Alarm Over-
ride Bit, Bank A,
Channel A. When
SDOVRIDE = 1, the
energy detector out-
put from the receiver
is masked. Thus,
when there is no
receive data, the
powerdown function
is disabled and the
corresponding
SDON alarm is sup-
pressed. SDOVRIDE
= 1 on device reset.
SDOVRIDE_AB
Receive Signal
Detect Alarm Over-
ride Bit, Bank A,
Channel B. When
SDOVRIDE = 1, the
energy detector out-
put from the receiver
is masked. Thus,
when there is no
receive data, the
powerdown function
is disabled and the
corresponding
SDON alarm is sup-
pressed. SDOVRIDE
= 1 on device reset.
SDOVRIDE_AC
Receive Signal
Detect Alarm Over-
ride Bit, Bank A,
Channel C. When
SDOVRIDE = 1, the
energy detector out-
put from the receiver
is masked. Thus,
when there is no
receive data, the
powerdown function
is disabled and the
corresponding
SDON alarm is sup-
pressed. SDOVRIDE
= 1 on device reset.
SDOVRIDE_AD
Receive Signal
Detect Alarm Over-
ride Bit, Bank A,
Channel D. When
SDOVRIDE = 1, the
energy detector out-
put from the receiver
is masked. Thus,
when there is no
receive data, the
powerdown function
is disabled and the
corresponding
SDON alarm is sup-
pressed. SDOVRIDE
= 1 on device reset.
8B10BR_AA
Receive 8B/10B
Decoder Enable Bit,
Bank A, Channel A.
When 8B10BR = 1,
the 8B/10B decoder
on the receive path
is enabled. Other-
wise, it is bypassed.
8B10BR = on device
reset.
LINKSM_AA
Link State Machine
Enable Bit, Bank A,
Channel A. When
LINKSM = 1, the
receiver link state
machine is enabled.
Otherwise, the link
state machine is dis-
ables. LINKSM = 0
on device reset.

RXHR_AB
Receive Half Rate
Selection Bit, Bank
A, Channel B. When
RXHR = 1, the
RBC[1:0] clocks are
issued at half the
scheduled rate of the
reference clock.
RXHR = 0 on device
reset.
PWRDNR_AB
Receiver Power
Down Control Bit,
Bank A, Channel B.
When PWRDNR =
1, sections of the
receive hardware
are powered down to
conserve power.
PWRDNR = 0 on
device reset.
8B10BR_AB
Receive 8B/10B
Decoder Enable Bit,
Bank A, Channel B.
When 8B10BR = 1,
the 8B/10B decoder
on the receive path
is enabled. Other-
wise, it is bypassed.
8B10BR = on device
reset.
LINKSM_AB
Link State Machine
Enalbe Bit, Bank A,
Channel B. When
LINKSM = 1, the
receiver link state
machine is enabled.
Otherwise, the link
state machine is dis-
ables. LINKSM = 0
on device reset.

RXHR = 1, the
RBC[1:0] clocks are
issued at half the
scheduled rate of the
reference clock.
RXHR = 0 on device
reset.
PWRDNR_AC
Receiver Power
Down Control Bit,
Bank A, Channel C.
When PWRDNR =
1, sections of the
receive hardware
are powered down to
conserve power.
PWRDNR = 0 on
device reset.
8B10BR_AC
Receive 8B/10B
Decoder Enable Bit,
Bank A, Channel C.
When 8B10BR = 1,
the 8B/10B decoder
on the receive path
is enabled. Other-
wise, it is bypassed.
8B10BR = on device
reset.
LINKSM_AC
Link State Machine
Enalbe Bit, Bank A,
Channel C. When
LINKSM = 1, the
receiver link state
machine is enabled.
Otherwise, the link
state machine is dis-
ables. LINKSM = 0
on device reset.
