|---|---|---|---|---|

| 14 | BIST Error Counter Mode | RW | 0 | BIST Error Counter Mode:
1 = Continuous mode, when the BIST Error counter reaches its max value, a pulse is generated and the counter starts counting from zero again. 0 = Single mode, when BIST Error Counter reaches its max value, PRBS checker stops counting. |
| 13 | PRBS Packet Type | RW | 0 | PRBS Packet Type:
1 = When packet generator is enabled (Bit[12] = '1'), generate continuous packets with PRBS data. When packet generator is disabled, PRBS checker is still enabled. 0 = When packet generator is enabled, generate single packet with constant data. PRBS gen/check is disabled. |
| 12 | Packet Generation Enable | RW | 0 | Packet Generation Enable:
1 = Enable packet generator with PRBS data 0 = Disable packet generator |
| 11 | PRBS Checker Lock/Sync | RO | 0 | PRBS Checker Lock/Sync Indication:
1 = PRBS checker is locked and synced on received bit stream 0 = PRBS checker is not locked |
| 10 | PRBS Checker Sync Loss | RO, LH | 0 | PRBS Checker Sync Loss Indication:
1 = PRBS checker has lost sync 0 = PRBS checker has not lost sync |
| 9 | Packet Generator Status | RO | 0 | Packet Generation Status Indication:
1 = Packet Generator is active and generating packets 0 = Packet Generator is off |
| 8:7 | Reserved | RO | 10 | Reserved |
| 6:2 | Loopback Select | RW | 0 | Loopback Select:
Bits[5:2] 0000 = Normal operation 0001 = PCS Loopback 0010 = Analog Loopback 0100 = Reverse Loopback 1000 = Reserved Bit[6]: 1 = Transmit data to the MDI in xMII Loopback 0 = Surpress data to the MDI in xMII Loopback Note: Bit[6] can only can be set in xMII Loopback |
