Description

General Purpose
When the correspondent bit of General Purpose Control Register is 1, the value of
the bit is output to pin GEPIO6-1
When the correspondent bit of General Purpose Control Register is 0, the value of
the bit be read is reflected from correspondent pins of GEPIIO6-1
The GEPIOs are mapped to pins GEPIO6 to GEPIO1 respectively
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.
