serial management interface (SMI) registers
to their default state, except for sticky and
super sticky bits.
1 = Reset asserted.
0 = Reset de-asserted.
You must wait 4 µs after setting this bit to
initiate another SMI register access.
0 = Loopback disabled.
When loop back is enabled, the device
functions at the current speed setting and
with the current duplex mode setting (bit 8
of this register).
00 = 10 Mbps.
01 = 100 Mbps.
10 = 1000 Mbps.
11 = Reserved.
1 = Auto-negotiation enabled.
0 = Auto-negotiation disabled.
Description
This is a self-clearing bit that restores all
1 = Loopback enabled.
LSB = bit 13, MSB = bit 6.
