PAR register (register 3)
The PAR register indicates the presence of the parti-
tioned ports and the port ID. A port can be automati-
cally partitioned if there is a consecutive false carrier
event, an excessive collision or a jabber. This register
is automatically cleared after each read. Table-7.3 lists
all the bits of this register.
PMERR register (register 4)
The PMERR register indicates the presence of PHYs
that have failed to respond to the PHY Management
command issued through the MDIO line. This register
is automatically cleared after each read. Table-7.4
describes all the bit of this register.
