Descriptions

EEPROM selection pin. EpSel is to determine which type of EEPROM is

97

I chosen. 93C46 is used when EpSel connects to VSS, while 93C66 is

selected if EpSel connects to VDD.

ISOLATION pin. This pin should connect to the PCI stable power signal

(VDD). When PCI Bus is in B3 state, the power signal becomes deas-

91

I serted, however the ISOLATION pin is active. Under this condition, the

PCIRST# and PCICLK are ignored and all the PCI output signals except

PME# are isolated from the PCI Bus.

Reset Output pin. A active-low pulse is generated when Power-On or

92

O

Hardware reset is detected. The pulse width is 245us. The PHY can use

this output pin as its reset signal, then PHY can avoid to keep being reset

during D3 state.
