PRBS_CTRL_0

PRBS_MON_MANUAL_

START

1:1

ROSW

Enable for manual timed measurement

using the Re-time PRBS checker.

01b: Triggers a scan

Automatically cleared to 0 when the scan

completes.

PRBS_MON_AUTO_SCAN_

START

0:0

ROSW

Enable for automatic eye scan using the

Re-time PRBS checker.

01b: Triggers a scan

Automatically cleared to 0 when the scan

completes.

3Bh

PRBS_CTRL_1

PRBS_MON_CONTINUOUS_

ENABLE

1:1

Enable for manual continuous

measurement using the Re-time PRBS

checker. Rising edge clears the error counter

and starts a measurement. Error counting

continues until

PRBS_MON_CONTINUOUS_ENABLE is set to

0, at which point the error counter

PRBS_MON_ERROR_COUNT can be read.

The error counter holds its value until any

new scan is started (manual or auto).

PRBS_MON_SOFT_RESET

0:0

When HIGH, the logic in PRBS monitor state

machine is synchronously reset.

3Ch

PRBS_CTRL_2

PRBS_MON_MEASUREMENT_

PREDIVIDER

7:4

Along with

PRBS_MON_MEASUREMENT_TIME,

determines the length of time of a

measurement for a given phase in

automatic or manual timed modes

(PRBS_MON_AUTO_SCAN_START = 1 or

PRBS_MON_MANUAL_START = 1).

Pre-divider value vs. sampling interval:

0000b: 4

0001b: 8

0010b: 16

0011b: 32

0100b: 64

0101b: 128

0110b: 256

0111b: 512

1000b: 1024

1001b: 2048

1010b-1111b: INVALID

PRBS_MON_SAMPLE_

INTERVAL

3:0

Controls sampling interval for an error

signal. The sampling interval is

PRBS_MON_SAMPLE_INTERVAL + 1 clock

cycles. The minimum allowable value is 1

(sampling interval of 2).
