PCIe Serial Data Input
Serial differential input link in the PCIe interface running at
2.5 Gb/s. The embedded clock present in this input is
recovered along with the data.
Wake
The 82574L drives this signal to zero when it detects a wake-
up event and either:
JTAG TDO Output.
Power and Clock Good Indication
The PE_RST_N signal indicates that both PCIe power and
clock are available.
• The PME_en bit in PMCSR is 1b or
• The APME bit of the Wake Up Control (WUC) register is
Serial Data Output
Connect this lead to the input of the Non-Volatile Memory
(NVM).
Note: The NVM_SI port pin includes an internal pull-up
resistor.
