Table 527. Remote Confirmation Packet Functions (Continued)
FIELD NAME
DESCRIPTION
ACKCODE
Packet control token - This 5-bit field holds the acknowledge code sent by the receiver for the current
packet. See Table 510 for a list of ACK codes.
PAD
Packet control token - Number of padding bytes added
SPD
Packet control token - The spd field indicates the speed at which the current packet was sent.
00 = 100 Mbps, 01 = 200 Mbps, 10 = 400 Mbps, and 11 is undefined for this implementation.
RSVD
Reserved
00
The 00 field is the PHY packet identifier.
PHY_ID
Physical node identifier of the destination of this packet
TYPE
Extended PHY packet type: (1010b indicates confirmation packet)
PORT
This field will specify the PHY port to which this packet pertains.
FAULT
Abbreviated as F in Figure 529. This bit is the current value of the fault bit from PHY register 1000b
for the addressed port.
CONNECTED
Abbreviated as C in Figure 529. This bit is the current value of the connected bit from PHY register
1000b for the addressed port.
BIAS
Abbreviated as B in Figure 529. This bit is the current value of the bias bit from PHY register 1000b
for the addressed port.
DISABLED
Abbreviated as D in Figure 529. This bit is the current value of the disabled bit from PHY register
1000b for the addressed port.
OK
Set to 1 if the command was accepted by the PHY. Set to 0 otherwise.
CMND
The CMND value (from the preceding remote command packet) with which this confirmation packet
is associated.
5.7.5
Resume Packet
ceLynx transmits a broadcast resume packet to commence operation on any node that is both connected
and suspended. The link logic automatically attaches the logical inverse second quadlet.

Figure 530. Resume Packet
Table 528. Resume Packet Functions
FIELD NAME
DESCRIPTION
00
The 00 field is the PHY packet identifier.
PHY_ID
Physical node identifier of the source of this packet
TYPE
Extended PHY packet type (1111b) indicates command packet
5.8
Receive Self-ID Packet
The self-ID packets can be either ignored or received into the data buffer based on the RCVSID bits in the
RXDPB(N)CFG1. The user must select which data buffer receives the self-IDs. This can be set in the
RXDPB(N)CFG1 register, bit 9. The default setting is self-ID packets routed to data buffer 6 and accessed
by the microprocessor port. The RXSIDFULL bit in register 0x300 enables ceLynx to receive both quadlets
in the selected data buffer; the self-ID and its inverse. Refer to Table 533.
