|Reserved||BIST Error Counter Mode||PRBS Packet Type||Packet Generation Enable||PRBS Checker Lock/Sync||PRBS Checker Sync Loss||Packet Generator Status||Reserved|
|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 = '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
|6:2||Loopback Select||RW||0|| Loopback Select:
0000 = Normal operation
0001 = PCS Loopback
0010 = Analog Loopback
0100 = Reverse Loopback
1000 = Reserved
1 = Transmit data to the MDI in xMII Loopback
0 = Surpress data to the MDI in xMII Loopback
Note: Bit can only can be set in xMII Loopback
