NODATA

9RO

0 = Normal



1 = No data transitions were seen

during the previous PRBS check

This bit is set to 1 to indicate that the

input data was all 0’s during a PRBS

check. When that happens, the error

count will be zero when in fact there

was no valid PRBS pattern.

This bit is updated by the device on

completion of a measurement. It

retains its value until the next PRBS

check operation is requested. Value is

undefined in case of abort

(STAT_PRBS_CHECK_LAST_ABORT = 1).

Value does not increment during a

measurement until it completes.

STAT_PRBS_CHECK_



LAST_ABORT

8RO
