1:0 | 00b | RW | Pad Ownership (PAD_OWN_GPD_0) 00 = Host GPIO ACPI Mode or GPIO Driver Mode. Host software (ACPI or GPIODriver) has ownership of the pad. In Host GPIO Driver Mode (refer toHOSTSW_OWN), GPIO input event update is limited to GPI_STS update only.Otherwise in Host ACPI Mode, updates are limited to GPI_GPE_STS, GPI_NMI_STSand/or GPI_SMI_STS. |
