Full-duplex Interrupt Mask
When this bit is set, the Duplex status change will not generate the
interrupt
Speed Interrupt Mask
When this bit is set, the Speed status change will not generate the
interrupt
Link Interrupt Mask
When this bit is set, the link status change will not generate the
interrupt
Master Interrupt Mask
When this bit is set, no interrupts will be generated under any
condition
Reserved
Duplex Status Change Interrupt
“1” indicates a change of duplex since last register read. A read of
this register will clear this bit
Speed Status Change Interrupt
“1” indicates a change of speed since last register read. A read of
this register will clear this bit
Link Status Change Interrupt
“1” indicates a change of link since last register read. A read of this
register will clear this bit
Reserved
Interrupt Status
The status of MDINTR#. “1” indicates that the interrupt mask is off
that one or more of the change bits are set. A read of this register
will clear this bit
Receive Error Counter
Receive error counter that increments upon detection of RXER.
Clean by read this register.
Reserved
Disconnect Counter those increments upon detection of
disconnection. Clean by read this register.
