GGPP_​E4 / DEVSLP0

OD

Serial ATA Port [0] Device Sleep: This is an open-drain pin on the PCH side. PCH will tri-state this pin to signal to the SATA device that it may enter a lower power state (pin will go high due to Pull-up that’s internal to the SATA device, per DEVSLP specification). PCH will drive pin low to signal an exit from DEVSLP state.

GPP_​E5 / DEVSLP1

OD

Serial ATA Port [1] Device Sleep: This is an open-drain pin on the PCH side. PCH will tri-state this pin to signal to the SATA device that it may enter a lower power state (pin will go high due to Pull-up that’s internal to the SATA device, per DEVSLP specification). PCH will drive pin low to signal an exit from DEVSLP state.
