Registers
Ethernet Address Registers. No broadcast or multicast
packets are accepted in the OFF mode.
If one of these bits is set to one (Port Mode is ON), then
the corresponding port receives all packets that are sent
on the Ethernet, regardless of the address specified in
the Ethernet Address Registers. The ports also receive
all broadcast and multicast packets in the ON mode.
DUPLEX
PORT x Duplex Mode
These four bits configure the corresponding Ethernet
ports to half-duplex or full-duplex mode (0 = Half Duplex;
1 = Full Duplex). Bit 0 configures Port 0, Bit 1 configures
Port 1, etc.

Configuration
Register 1
Figure 2.2 shows the bit assignments for Configuration Register 1. This
16-bit register is read/write. To modify any of these bits, the processor
should perform a read-modify-write operation in order to retain the values
of the non-affected bits in this register.

Configuration Register 1
WEP
Write Enable Port
Setting this bit to one enables writing to the four bits in
the ENPORTx field in the Packet Configuration Register.
The ENPORTx field enables/disables the four ports.

DIAG
Diagnostic Modes
These bits determine the type of mode in which the
L64381 operates.
