1 -> AN 100Base-TX full-duplex selected
0 -> AN 100Base-TX full-duplex not selected
1 -> AN 100Base-T4 selected (not supported)
0 -> AN 100Base-T4 not selected
Internally fixed to '0'
1 -> AN 100Base-TX half-duplex selected
0 -> AN 100Base-TX half-duplex not selected
1 -> AN 10Base-T full-duplex selected
0 -> AN 10Base-T full-duplex not selected
1 -> AN 10Base-T half-duplex selected

---
1 -> Restarts auto-negotiation process (ignored if auto-
negotiation is disabled)
0 -> Normal operation
Self-cleared after 21MHz-clock periods (auto-negotiation
is started). Same as RN00_CNTRL[9]
1 -> Auto-negotiation process completed
0 -> Auto-negotiation process not completed
Active only if auto-negotiation is enabled, else 0
Same as RN19_AUXSS[15] and RN01_STATS[5]
1 -> AN ack completed
0 -> AN ack not yet completed
Held high until tx is disabled or auto-negotiation is
restarted
1 -> AN first ack received
0 -> AN first ack not yet received
Held high until tx is disabled or auto-negotiation is
restarted
1 -> Auto-negotiation in ability detect state
0 -> Auto-negotiation not in ability detect state
Same as RN19_AUXSS[12]
SUPER ISOLATE:
1 -> MII and RX isolated
0 -> Normal operation
All MII inputs are ignored, all MII outputs are tri-stated, no
link pulses generated.
Same effect setting to 1 both RN00[10] and RN13[5].
