abort (RTABORT, bit 12) occurs.
SINT is cleared by H_RESET or
S_RESET and is not affected by
setting the STOP bit.
System Interrupt Enable. If
SINTE is set, the SINT bit will be
able to set the INTR bit.
Read/Write accessible always.
SINTE is cleared to ZERO by
H_RESET or S_RESET and is
not affected by setting the
STOP bit.
Sleep Interrupt is set by the
PCnet-PCI II controller when it
comes out of sleep mode.
When SLPINT is set,
INTA
is as-
serted if the enable bit SLPINTE
is ONE. Note that the assertion of
an interrupt due to SLPINT is not
dependent on the state of the
INEA bit, since INEA is cleared
by S_RESET when entering the
sleep mode.
Read/Write accessible always.
SLPINT is cleared by the host by
writing a ONE. Writing a ZERO
has no effect. SLPINT is cleared
by H_RESET and is not affected
by S_RESET or by setting the
STOP bit.
Sleep
Interrupt
SLPINTE is set, the SLPINT bit
will be able to set the INTR bit.
Read/Write accessible always.
SLPINTE is cleared to ZERO by
H_RESET and is not affected by
S_RESET or by setting the
STOP bit.
Excessive Deferral Interrupt is
set by the PCnet-PCI II controller
when the transmitter has experi-
enced Excessive Deferral on a
transmit frame, where Excessive
Deferral is defined in ISO 8802-3
(IEEE/ANSI 802.3).
When EXDINT is set,
INTA
is as-
serted if the enable bit EXDINTE
is ONE.
Read/Write accessible always.
EXDINT is cleared by the host by
writing a ONE. Writing a ZERO
has no effect. EXDINT is cleared
by H_RESET and is not affected
by S_RESET or by setting the
STOP bit.
Excessive Deferral Interrupt En-
able. If EXDINTE is set, the EX-
DINT bit will be able to set the
INTR bit.

Magic Packet Physical Logical
Broadcast Accept. If MPPLBA is
cleared to ZERO, the PCnet-PCI
II controller will only detect a
magic packet if the destination
address of the packet matches
the content of the physical ad-
dress
register
MPPLBA is set to ONE, the desti-
nation address of the magic
packet can be unicast, multicast
or broadcast. Note that the set-
ting of MPPLBA only effects the
address detection of the magic
packet. The magic packet data
sequence must be in all cases
the same, i.e., a 16-times repeti-
tion of the the physical address
(PADR[47:0]).
Read/Write accessible always.
MPPLBA is cleared to ZERO
by H_RESET or S_RESET and
is not affected by setting the
STOP bit.

MPINT
Magic Packet Interrupt is set by
the PCnet-PCI II controller
when the device is in magic
packet mode and it receives a
magic packet.
When MPINT is set,
INTA
is as-
serted if IENA (CSR0, bit 6) and
the enable bit MPINTE are set
to ONE.
Read/Write accessible always.
MPINT is cleared by the host by
writing a ONE. Writing a ZERO
has no effect. MPINT is cleared
by H_RESET, S_RESET or by
setting the STOP bit.
Magic Packet Interrupt Enable. If
MPINTE is set, the MPINT bit will
be able to set the INTR bit.
Read/Write accessible always.
MPINTE is cleared to ZERO by
H_RESET or S_RESET and is
not affected by setting the
STOP bit.
Magic Packet Enable. MPEN al-
lows activation of the magic
packet mode by software. The
PCnet-PCI II controller will enter
the magic packet mode when
both MPEN and MPMODE are
set to ONE.
