0_h Reserved. Do not change.
Enables a continuous, manually timed
horizontal eye scan using the parameters
defined in EYE_MON_CONTROL_REG_[0:6]
registers.
Setting CONTINUOUS_SCAN_ENABLE to 1
clears the ERROR_COUNT bits and starts a
new measurement.
0_h
Error counting continues until
CONTINUOUS_SCAN_ENABLE is set to 0, at
which point the ERROR_COUNT bits may be
read.
The ERROR_COUNT bits hold their value
until any new scan is started using
AUTO_SCAN_START,
MANUAL_SCAN_START, or
CONTINUOUS_SCAN_ENABLE.
Synchronous soft-reset for the horizontal
eye monitor block and its associated
registers (EYE_MON_CONTROL_REG_[0:6]
0_h ^{and EYE_MON_STATUS_REG_[2:12]).}
00_b: Normal operation of the horizontal eye
monitor
01_b: Resets the horizontal eye monitor
0_h Reserved. Do not change.
Selects the pre-divider value for the
sampling interval.

1000_b: 1024
1001_b: 2048
1010_b-1111_b: INVALID
This parameter, combined with
MEASUREMENT_TIME, defines the length of
time per phase for an auto eye scan
Controls the sampling interval in device
clock cycles.
2_{h Sampling interval = SAMPLE_INTERVAL + 1}
device clock cycle.
