BitFieldTypeResetDescription
15:14ReservedR0x0
13 PRBS_Sync_LossR/WoC0x0

1b = PRBS has locked

0b = PRBS has not locked

12Pkt_DoneR0x0Set when all MAC packets with CRC are transmitted
11Pkt_Gen_BusyR0x0

1b = Packet generator is in process

0b = Packet generator is not in process

10PRBS_Pkt_OvR0x0

If set, packet counter reached overflow

Overflow is cleared when PRBS counters are cleared - done by setting bit[1] of 0x011F

9PRBS_Byte_OvR0x0

If set, bytes counter reached overflow

Overflow is cleared when PRBS counters are cleared - done by setting bit[1] of 0x011F

8PRBS_LockR0x0

1b = PRBS checker is locked (sync) on received byte stream

0b = PRBS checker is not locked

7:0PRBS_Err_CntR0x0

Holds number of errored bits received by the PRBS checker

Value in this register is locked when write is done to bit[0] or bit[1]

When PRBS Count Mode set to zero, count stops on 0xFF

Notes: Writing bit 0 generates a lock signal for the PRBS counters.

Writing bit 1 generates a lock and clear signal for the PRBS counters
