the description of the LOOP bit
in CSR15.
Read/write
accessible
when STOP or SPND bits are
set.
Low Receive Threshold (T-MAU
Mode only)
Transmit Mode Select (AUI
Mode only)
Low Receive Threshold. When
LRT =
1", the internal twisted
pair receive thresholds are
reduced by 4.5 dB below the
standard
10BASE-T
(approximately 3/5) and the
unsquelch threshold for the RXD
circuit will be 180-312 mV peak.
When LRT =
0", the unsquelch
threshold for the RXD circuit will
be the standard 10BASE-T
value, 300-520 mV peak.
In either case, the RXD circuit
post squelch threshold will be
one half of the unsquelch thresh-
old.
This bit only has meaning when
the 10BASE-T network interface
is selected.
Read/write
accessible
when STOP or SPND bits are
set. Cleared by RESET.
Transmit Mode Select. TSEL
controls the levels at which the
AUI drivers rest when the AUI
transmit port is idle. When TSEL
= 0, DO+ and DO- yield
zero
dif-
ferential to operate transformer
coupled loads (Ethernet 2 and
802.3). When TSEL = 1, the DO+
idles at a higher value with
respect to DO-, yielding a logical
HIGH state (Ethernet 1).
This bit only has meaning when
the AUI network interface is
selected. Not available under
Auto-Select Mode.
Read/write
accessible
when STOP or SPND bits are
set. Cleared by RESET.
Port Select bits allow for software
controlled selection of the net-
work medium. PORTSEL active
only when Media-Select Bit set
to 0 in ISACSR2.
Read/write
accessible
when STOP or SPND bits are
set. Cleared by RESET.

Internal Loopback. See the
description of LOOP, CSR15.2.
Read/write
accessible
when STOP bit is set.
Disable Retry. When DRTY =
1", PCnet-ISA II controller will
attempt only one transmission. If
DRTY =
0", PCnet-ISA II con-
troller will attempt to transmit 16
times before signaling a retry
error.
Read/write
accessible
when STOP or SPND bits are
set.
Force Collision. This bit allows
the collision logic to be tested.
PCnet-ISA II controller must be
in internal loopback for FCOLL
to be valid. If FCOLL =
1", a col-
lision will be forced during loop-
back transmission attempts; a
Retry Error will ultimately result.
If FCOLL =
0", the Force Colli-
sion logic will be disabled.
Read/write
accessible
when STOP or SPND bits are
set.
Disable Transmit CRC (FCS).
When DXMTFCS =
0", the
transmitter will generate and
append a FCS to the transmitted
frame. When DXMTFCS =
1",
the FCS logic is allocated to the
receiver and no FCS is generat-
ed or sent with the transmitted
frame.
See also the ADD_FCS bit in
TMD1. If DXMTFCS is set, no
FCS will be generated. If both
DXMTFCS is set and ADD_FCS
is clear for a particular frame, no
FCS
will
be
ADD_FCS is set for a particular
frame, the state of DXMTFCS is
ignored and a FCS will be ap-
pended on that frame by the
transmit circuitry.
