Default
0, RW/SC Reset:
Description
1=Software reset
0=Normal operation
This bit resets the status and controls the PHY registers of the DM9102D to
their default states. This bit, which is self-clearing, will keep its value until the
reset process is completed
Loopback:
1=Loop-back enabled
0=Normal operation
When in 100Mbps operation mode, setting this bit may cause the
descrambler to lose synchronization and produce a 720ms "dead time" before
any valid data to the MAC.
Speed Select:
1=100Mbps
0=10Mbps
Link speed may be selected either by this bit or by Auto-negotiation. When
Auto-negotiation is enabled and bit 12 is set, this bit will reflect Auto-
negotiation selected media type.
Auto-negotiation Enable:
1= Auto-negotiation enabled: bit 8 and 13 will report Auto-negotiation status
0= Auto-negotiation disabled: bit 8 and 13 will determine the link speed and
duplex mode
Power Down:
Setting this bit will power down the internal PHY except crystal / oscillator
circuit.
1=Power Down
0=Normal Operation
Reserved.
Write as 0, ignore on read.
0,RW/SC Restart Auto-negotiation:
1= Restart Auto-negotiation. Re-initiates the Auto-negotiation process. When
Auto-negotiation is disabled (bit 12 of this register cleared), this bit has no
function and it should be cleared. This bit is self-clearing and it will keep
its value until Auto-negotiation is initiated by the DM9102D. The operation of
the
Auto-negotiation
process
management entity that clears this bit.
0= Normal Operation
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,RW
Collision Test:
1= Collision Test enabled. When set in half duplex mode, the DM9102D will
enter collision state if packet transmission is in progress.
0= Normal Operation
