Signal Type Definitions
The signals of the 82546GB controller are electrically defined as follows:
then damage to the Ethernet controller is likely to occur. TTL inputs include the JTAG interface
pins, the FLASH interface pins, the EEPROM interface pins, the LED pins, the software definable
pins, and the LAN_PWR_GOOD pin.
PCI Bus Interface
When the Reset signal (RST#) is asserted, the 82546GB will not drive any PCI output or bi-
directional pins except the Power Management Event signal (PME#).

Input. Standard input only digital signal.
Output. Standard output only digital signal.
Tri-state. Bi-directional three-state digital input/output signal.
Sustained Tri-state. Sustained digital three-state signal driven by one agent at a time.
An agent driving the STS pin low must actively drive it high for at least one clock before letting
it float. The next agent of the signal cannot drive the pin earlier than one clock after it has been
released by the previous agent.
Open Drain. Wired-OR with other agents.
The signaling agent asserts the OD signal, but the signal is returned to the inactive state by a
weak pull-up resistor. The pull-up resistor may require two or three clock periods to fully restore
the signal to the de-asserted state.
Analog. PHY analog data signal.
Power. Power connection, voltage reference, or other reference connection.
