Reserved bits: Ignore ST802RT1x output when these bits are read.
Preamble suppression: This bit is a read-only bit and can be set by bit 1 of the RN14
register. When read as a logic “1”, the ST802RT1x is able to accept MII management
frames with or without the standard preamble pattern. When preamble suppression is
enabled (RN14[1]=1), only 2 preamble bits are required between successive management
commands, instead of the normal 32.
Auto-negotiation complete: Bit 5 of the status register returns a “1” if the auto-negotiation
process has been completed, and the contents of registers 4, 5, and 6 are valid.
Link status: The ST802RT1x returns a “1” on bit 2 of the status register when the link state
machine is in link pass, indicating that a valid link has been established. Otherwise, it
returns a “0”. When a link failure occurs after the link pass state has been entered, the link
status bit is latched at “0” and remains so until the bit is read. After the bit is read, it becomes
“1” if the link pass state has been entered again.
Jabber detect: 10BASE-T operation only. The ST802RT1x returns a “1” on bit 1 of the
status register if a jabber condition has been detected. After the bit is read, or if the chip is
reset, it reverts to “0”.
Extended register ability: Because the ST802RT1x supports extended register capability,
this read-only bit is always “1”. The ST802RT1x extended registers with their bit functions
are described in later sections of this document.
The PHY identifier registers #1 and #2 consist of a sum of the organizationally unique
identifier (OUI), the vendor's model number and the model revision number. ST's IEEE
assigned OUI is 0x0080E1.
