Read/Write
when either the STOP or the
SPND bit is set.
Disable Transmit CRC (FCS).
When DXMTFCS is cleared to
ZERO,
the
transmitter
generate and append an FCS to
the transmitted frame. When
DXMTFCS is set to ONE, no FCS
is generated or sent with the
transmitted frame. DXMTFCS is
overridden when ADD_FCS is
set in TMD1.
If
DXMTFCS
ADD_FCS is clear for a particular
frame, no FCS will be generated.
The value of ADD_FCS is valid
only when STP is set in TMD1. If
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. See also the
ADD_FCS bit in TMD1.
This bit is called DTCR in the
C-LANCE (Am79C90).
Read/Write
accessible
when either the STOP or the
SPND bit is set.
Loopback
Enable
PCnet-PCI II controller to oper-
ate in full-duplex mode for test
purposes. The setting of the
full-duplex control bits in BCR9
have no effect when the device
operates in loopback mode.
When LOOP is set to ONE,
loopback is enabled. In combina-
tion with INTL and MENDECL,
various loopback modes are
defined
in
the
Configuration table.
Read/Write
accessible
when either the STOP or the
SPND bit is set. LOOP is cleared
by H_RESET or S_RESET and is
unaffected
by
STOP bit.
Disable Transmit. When DTX is
set to ONE, the PCnet-PCI II con-
troller will not access the transmit
descriptor ring and therefore no
transmissions are attempted.
When DTX is cleared to ZERO,
TXON (CSR0, bit 4) is set to ONE
after STRT (CSR0, bit 1) has
been set to ONE.
Read/Write
accessible
when either the STOP or the
SPND bit is set.

DRX
Disable Receiver. When DRX is
set to ONE, the PCnet-PCI II con-
troller will not access the receive
descriptor ring and therefore all
receive frame data are ignored.
When DRX is cleared to ZERO,
RXON (CSR0, bit 5) is set to
ONE after STRT (CSR0, bit 1)
has been set to ONE.
Read/Write

when either the STOP or the
