Reserved. Do not change.

CONTINUOUS_SCAN_

ENABLE

1:1

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.

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.

EYE_MON_SOFT_RESET

0:0

Synchronous soft-reset for the horizontal

eye monitor block and its associated

registers (EYE_MON_CONTROL_REG_[0:6]

and EYE_MON_STATUS_REG_[2:12]).

00b: Normal operation of the horizontal eye

monitor

01b: Resets the horizontal eye monitor

MEASUREMENT_

PREDIVIDER

7:4

Selects the pre-divider value for the

sampling interval.

0000b: 4

0001b: 8

0010b: 16

0011b: 32

0100b: 64

1000b: 1024

1001b: 2048

1010b-1111b: INVALID

This parameter, combined with

MEASUREMENT_TIME, defines the length of

time per phase for an auto eye scan

SAMPLE_INTERVAL

3:0

Controls the sampling interval in device

clock cycles.

Sampling interval = SAMPLE_INTERVAL + 1

device clock cycle.
