EYE_MON_CLEAR
Override value for EYE_MON_PRBS_CLEAR.

0_{h Only used when}
EYE_MON_FORCE_PRBS_CLEAR = 1.
01_b: Overrides the EYE_MON_CLEAR output
with the PRBS_MON__CLEAR value
EYE_MON_FORCE_CLEAR
4:4
RW
0_{h Allows host interface to directly control the}
PRBS/eye monitor bypassing the
PRBS_MON_CTRL state machines.
Override value for EYE_MON_PRBS_CLEAR.
EYE_MON_PRBS_CLEAR

EYE_MON_PRBS_FORCE_
CLEAR
2:2
RW
0_h ^value
Allows host interface to directly control the
PRBS/eye monitor bypassing the
EYE_MON_CTRL state machines.
EYE_MON_SELECT
Selects which criteria is used to populate the
eye bitmap.
1:1
RW
1_{h 00b: PRBS7 check}
01_b: Arbitrary data check
EYE_MON_WINDOW
Sets which portion of the eye is to be
sampled for manually timed and continuous
0:0 RW 0_h scan measurements. Result for the phase is
the lesser count of errors at each
EYE_MON_WINDOW setting.
RSVD
15:15 RO
0_h Reserved. Do not change.
EYE_MON_PRBS_STARTING_
PHASE
14:8
RO
Starting (leftmost) phase of
EYE_MON_PRBS_EYE_WIDTH in the most
0_h recent scan. This parameter only applies to
automatic (AUTO_SCAN_START)
measurements.
2C_h
EYE_MON_
STATUS_REG_0
Widest open portion of the eye in the most
recent scan, based on the
EYE_MON_PRBS_ERROR_COUNT indication.
The value of EYE_MON_PRBS_EYE_WIDTH is
the number of contiguous phases with
EYE_MON_PRBS_EYE_WIDTH 7:0
RO
0_{h EYE_MON_PRBS_ERROR_COUNT less than}
or equal to
EYE_MON_PRBS_ERROR_THRESHOLD.
This parameter only applies to automatic
(AUTO_SCAN_START) measurements.
