DM9010
Single Chip Ethernet Controller with General Processor Interface
affected by the management entity that clears this bit
0 = Normal operation
0.8
Duplex mode
1,RW Duplex Mode
1 = Full duplex operation. Duplex selection is allowed when
Auto-negotiation is disabled (bit 12 of this register is cleared).
With auto-negotiation enabled, this bit reflects the duplex
capability selected by auto-negotiation
0 = Normal operation
0.7
Collision test
Reserved
0,RW Collision Test
1 = Collision test enabled. When set, this bit will cause the
COL signal to be asserted in response to the assertion of
TX_EN in internal MII interface.
0 = Normal operation
