BIST Sequence select: Selects length of LFSR used in BIST
1 = PSR15 selected
0 = PSR9 selected
BIST Test Status: Default: 0, LL/RO
1 = BIST pass
0 = BIST fail. Latched, cleared by write to BIST start bit.
BIST Start: BIST runs continuously until stopped. Minimum time to run should be 1 ms.
1 = BIST start
0 = BIST stop
Bypass LED Stretching:
This will bypass the LED stretching and the LEDs will reflect the internal value.
1 = Bypass LED stretching
0 = Normal operation
Pause Compare Status: Default: 0, RO
0 = Local Device and the Link Partner are not Pause capable
1 = Local Device and the Link Partner are both Pause capable
Reserved
PHY Address: Default: <11111b>, RW
PHY address for the port.
Signal Detect Option:
1 = Enhanced signal detect algorithm
0 = Reduced signal detect algorithm
Reserved: Read as 0
