DESCRIPTION
0-2
Reserved
N/A
Reserved
3
C
R/O
Bus manager capable. This bit is active when the PHY is ON even when the link is in reset. The bit defaults
to 1 and is is unaffected by a bus reset. This bit is determined by the CONTEND terminal defined in Section
2.
4
LKON
S/C
Link-on output from PHY. This bit is active when the PHY generates the LINKON signal, even when the link
is in reset. This bit is set when the PHY detects a LINKON packet. This bit defaults to 0 and is unaffected by
a bus reset.
5
LPS
R/O
Link power status. Setting this bit to 1 sets the internal PHY LPS signal to one. This bit defaults to 1 and is
unaffected by a bus reset. Refer to Section 11 for more detail.
6
Reserved
N/A
Reserved
7-15
Ping_Timer
R/O
Ping timer value. The timer measures the time in units from when a ping packet is transmitted to when the
ping response is received. One unit is 40ns.
16
Root
R/O
Root state of the local PHY. This bit indicates whether the node is the root node. The root bit is set to 1 when
the node is root. This bit defaults to 0 and is automatically set by the hardware.
17-22
Reserved
N/A
Reserved
23
AckErr
R/O
Acknowledge error. The AckErr bit is set when the ack received for the packet transmitted from the ATF
has a parity or length error.
24-27
ATAck
R/O
Address transmitter acknowledges received. These bits contain the last ack received in response to a
packet sent by the ATF. This value is updated each time an ack is received.
28-30
Reserved
N/A
Reserved
31
AckVld
R/O
Acknowledge valid. This bit is 1 when the ATAck has not been read and is cleared to 0 when the ATAck is
read.
