Enable for manual timed measurement

using the Re-time PRBS checker.
1:1 ROSW 0_h 01_b: Triggers a scan
Automatically cleared to 0 when the scan
3A_h
PRBS_CTRL_0
completes.
Enable for automatic eye scan using the
PRBS_MON_AUTO_SCAN_
START
Re-time PRBS checker.
0:0 ROSW 0_h 01_b: Triggers a scan
Automatically cleared to 0 when the scan
completes.
Enable for manual continuous
measurement using the Re-time PRBS
checker. Rising edge clears the error counter
and starts a measurement. Error counting
PRBS_MON_CONTINUOUS_
ENABLE

RW
continues until
0_{h PRBS_MON_CONTINUOUS_ENABLE is set to}
3B_h
PRBS_CTRL_1
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
RW
0_h
When HIGH, the logic in PRBS monitor state
machine is synchronously reset.
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).

PRBS_MON_SAMPLE_
INTERVAL
Controls sampling interval for an error
signal. The sampling interval is
3:0 RW 2_h PRBS_MON_SAMPLE_INTERVAL + 1 clock
cycles. The minimum allowable value is 1
(sampling interval of 2).
