TPB line state for the port (same encoding as AStat).
If equal to one, the port is a child; otherwise, a parent. The
meaning of this bit is undefined from the time a bus reset is
detected until the PHY transitions to state T1: Child Hand-
shake during the tree identify process (see Section 4.4.2.2 in
IEEE
Standard 1394-1995).
If equal to one, the port is connected.
If equal to one, incoming TPBIAS is detected.
If equal to one, the port is disabled.
Indicates the maximum speed negotiated between this PHY
port and its immediately connected port; the encoding is the
same as for they PHY register Max_speed field.
Enable port event interrupts. When set to one, the PHY will
set Port_event to one if any of connected, bias, disabled, or
fault (for this port) change state.
Set to one if an error is detected during a suspend or resume
operation. A write of one to this bit clears it to zero.
