Description
Hardware Suspend
HWSPND#
I
Hardware Suspend: This signal works as HWSPND# input. PCIRST# is not accepted
as long as HWSPND# is asserted so that VCC_PCI can be powered off. When Serial
IRQ mode is set, HWSPND# must be asserted after Serial IRQ mode on the chip-set
has been deasserted. When Hardware Suspend mode is off, HWSPND# must be
deasserted before Serial IRQ mode is enabled.
