describes the fields of the ANA register.
MPC8544E PowerQUICC III Integrated Host Processor Family Reference Manual, Rev. 1
describes the definition for the ANA register.
AN Advertisement Register (ANA)
Next page configuration. The local device sets this bit to either request next page transmission or advertise
next page exchange capability.
0 The local device wishes not to engage in next page exchange.
1 The local device has no next pages but wishes to allow reception of next pages. If the local device has no
Reserved. (Ignore on read)
Auto-negotiation complete. This bit is read-only and is cleared by default.
0 Either the auto-negotiation process is underway or the auto-negotiation function is disabled.
1 The auto-negotiation process has completed.
Remote fault. This bit is read-only and is cleared by default. Each read of the status register clears this bit.
0 Normal operation.
1 A remote fault condition was detected. This bit latches high in order for software to detect the condition.
Auto-negotiation ability. While read as set, this bit indicates that the PHY has the ability to perform
auto-negotiation. While read as cleared, this bit indicates the PHY lacks the ability to perform
auto-negotiation. Returns 1 on read. This bit is read-only.
Link status. This bit is read-only and is cleared by default.
0 A valid link is not established. This bit latches low allowing for software polling to detect a failure condition.
1 A valid link is established.
Reserved, should be cleared.
Extended capability. This bit indicates that the PHY contains the extended set of registers (those beyond
control and status). Returns 1 on read. This bit is read-only.

codes and have the message page set to 0b000_0000_0001, as defined in annex 28C.
