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. 4.18 Vendor ID Register (28H~29H) Bit Name Default Description 7:0 VIDH 0AH,RO Vendor ID high byte (29H) 7:0 VIDL 46H.RO Vendor ID low byte (28H) 4.19 Product ID Register (2AH~2BH) Bit Name Default Description 7:0 PIDH 96H,R Product ID high byte (2BH) 7:0 PIDL 20H.R Product ID low byte (2AH) 4.20 Chip Revision Register (2CH) Bit Name Default Description 7:0 CHIPR 01H,RO CHIP revision |
