2. PCI-E接口定义

说明:

Ground pin Zero volt reference
Power pin Supplies power to the PCIe card
Card-to-host pin Signal from the card to the motherboard
Host-to-card pin Signal from the motherboard to the card
Open drain May be pulled low or sensed by multiple cards
Sense pin Tied together on card
Reserved Not presently used, do not connect
