Reset to 00b.
Reset to 0b.
When set, this bit indicates that device transitioning from D3hot to D0 does
not perform an internal reset. When clear, an internal reset is performed when
power state transits from D3hot to D0. This bit can be rewritten with
EEPROM programming. The default value may be changed by SMBus or
auto-loading from EEPROM.
Reset to 1b.
Reset to 0b.
When asserted, the Switch will generate the PME# message. Reset to 0b.
Select data registers.
Reset to 0h.
Reset to 00b.
Read as 0b as the PME# message is not implemented.
