Description
RESET
Setting this bit initiates the software reset function that resets the selected
port, except for the phase-locked loop circuit. It will re-latch in all
hardware configuration pin values The software reset process takes
25
until the reset process is complete.

Loop Back Enable
This bit controls the PHY loopback operation that isolates the network
transmitter outputs (TXP and TXN) and routes the MII transmit data to the
MII receive data path. This function should only be used when auto
negotiation is disabled (bit 12 = 0). The specific PHY (10Base-T or
100Base-X) used for this operation is determined by bits 12 and 13 of this
register

Speed Selection LSB, 0.6, 0.13
Link speed is selected by this bit or by auto negotiation if bit 12 of this
register is set (in which case, the value of this bit is ignored).If it is fiber
mode, 0.13 is always 1. Any write to this bit will have no effect.
