The SIDEND bit in register 0x308 indicates the end of the self-ID period. The LINT.SELFIDERR interrupt
in register 0x044 indicates a self-ID error. This error can be decoded in the LCTRL.SIDERCODE bits in
register 0x040.
A packet control token is always attached to received self-ID packets. This control token gives information
on the receive status. See Figure 533 and Table 534 for packet control token format.

BIT NAME
DESCRIPTION
RSVD
Reserved
Size
Size of the packet in quadlets
S
This bit is set when the token is attached to a self-ID packet.
P
This bit is set when the token is attached to a PHY packet.
RSVD

ERR
When the packet control token is attached to a self-ID packet, this 3-bit field contains the self-ID
error code. The error codes are noted in the LCTRL register, bits 6:4.
000
No error
001
Last self-ID received was not all child ports.
010
Received PHY ID in self-ID was not as expected.
011
Quadlet not inverted (phase error)
100
PHY ID sequence error (two or more gaps in Ids)
101
PHY ID sequence error (large gap in packet)
110
PHY ID error within packet
111
Quadlet not the inversion of the prior quadlet
PAD
Number of bytes padded (e.g., data_length = 9, pad = 1)
SPD
Speed code of the received packet

X
Self-ID packets are not received by the link.

0
Only the data quadlet (first quadlet) of the self-ID packets are received into the selected data
buffer.
1
1
Both the data quadlet (first quadlet) and the logical inverse quadlet (second quadlet) of all
self-ID packets are received into the selected data buffer.
