Port event detect. The PHY sets this bit to one if any of
connected, Bias, Disabled or Fault change for a port whose
Int_enable bit is one. The PHY also sets this bit to one if resume
operations commence for any port and Resume_int is one. A
write of one to this bit clears it to zero.
Enable arbitration acceleration. When set to one, the PHY shall
use the enhancements specification in P1394A.
Enable multi-speed packet concatenation. When set to one, the
Link shall signal the speed of all packets to the PHY.
Selects which of eight possible PHY register pages are
accessible through the window at PHY register address 1000b
through 1111b, inclusive.
0000 If the page selected by Page_select presents per port
information, this field selects which port’s registers are
accessible through the window at PHY register addressed 1000b
through 1111b, inclusive.
