Fixed as output only. Main power well.
Fixed as Output only. Main power well. Can be used instead as PC/PCI GNT[A:B]#.
GPIO17 can also alternatively be used for PCI GNT5#. Integrated pull-up resistor.
Fixed as Input only. Resume power well. Can be used instead as OC[7:6]#.
Fixed as Input only. Resume power well. Not multiplexed.
Fixed as Input only. Resume power well. Can be used instead as SMBALERT#.
Fixed as Input only. Resume power well. Can be used instead as OC[5:4]#.
Fixed as Input only. Resume power well. Not multiplexed. This GPIO is recommended
for use as the Communications Streaming Architecture (CSA) PME# signal to provide
Wake-On-LAN capabilities. The GPI_INV bit corresponding to GPIO8 must be set in
order to achieve the correct polarity in the General Purpose Event 0 Status Register.
Fixed as Input only. Main power well. Not multiplexed.
Fixed as Input only. Main power well.
Fixed as Input only. Main power well. Can be used instead as PIRQ[E:H]#.
Fixed as Input only. Main power well. Can be used instead as PC/PCI REQ[A:B]#.
GPIO1 can also alternatively be used for PCI REQ5#.
