General purpose :
When the correspondent bit of General Purpose Control Register is 1, the
value of the bit is output to pin GEPIO0.
When the correspondent bit of General Purpose Control Register is 0, the
value of the bit be read is reflected from pin GEPIO0.
GEPIO0 default output 1 to POWER_DOWN internal PHY. Driver need to
clear this POWER_DOWN signal by write “0” when it wants PHY active. If
other device need, it also can refer this signal. This default value can be
programmed by EEPROM. Please refer EEPROM description.
