Table B–4. ThunderLAN PHY Status Register Bits
Bit Name Function
15 MINT MII interrupt: This bit indicates an MII interrupt condition. The MII interrupt request is
activated whenever this bit is set to 1. The bit may be cleared and the interrupt deas-
serted by writing a 1 to this bit position. Writing a 0 to this bit has no effect.
This bit is set to 1 when:
The state of the PHOK, LINK, JABBER, RETRAIN TRFRTO, RTRIDL, or LSIL
changes
RFLT is set to 1
The condition for the interrupt can be determined by examining these bits. In the case
of LINK, which could change before the interrupt type can be determined,
ThunderLAN keeps this bit as 0 until it is read, even if the link is restored. This is to
ensure that the condition change is not lost.
14 PHOK Power high OK: This bit is reserved for future use.
13–12 Reserved Read as 0s
11–8 CONFIG Configuration bits: These bits indicate the type of PMD attached to the PMI device.
7 Reserved Read as 0
6 RETRAIN Retrain link: This bit, when set, indicates that the link must be retrained. It is set if the
link has been silent too long, bad RLS codes have been detected, training idles have
been received from the hub, or Rx or Tx jabber has been detected. If the INTEN bit is
also set, this causes an MII interrupt.
5–4
LSTATE Link state: This field returns the PMD current link state bits. It is used for informational
purposes only.
00: Link is silent
01: Data on link
10: Control on link
11: Bad RLS code on link
