BPV_INS
6
0
BPV error insertion
A ‘0’ to ‘1’ transition on this bit will cause a single bipolar violation error to be inserted into the transmit data
stream. This bit must be cleared and set again for a subsequent error to be inserted.
ERR_INS
5
0
PRBS/QRSS logic error insertion
A ‘0’ to ‘1’ transition on this bit will cause a single PRBS/QRSS logic error to be inserted into the transmit PRBS/
QRSS data stream. This bit must be cleared and set again for subsequent error to be inserted.
EXZ_DEF
4
0
EXZ definition select
= 0: ANSI
= 1: FCC
ERR_SEL
3-2
00
These bits choose which type of error will be counted
= 00: the PRBS logic error is counted by a 16-bit error counter.
= 01: the EXZ error is counted by a 16-bit error counter.
= 10: the Received CV (BPV) error is counted by a 16-bit error counter.
= 11: both CV (BPV) and EXZ errors are counted by a 16-bit error counter.
CNT_MD
1
0
Counter operation mode select
= 0: Manual Report Mode
= 1: Auto Report Mode
CNT_TRF
0
= 0: Clear this bit for the next ‘0’ to ‘1’ transition on this bit.
= 1: Error counting result is transferred to CNT0 and CNT1 and the error counter is reset.
