y Value (y values may be ORed together to get the desired combination of features)

0x01

Falling edge

0x02

Rising edge

0x04

Power button

0x08

Reserved

Note: For GPIO mapping, a value of 0000zyxx is used where:

z = a runtime/wake indicator

y = the edge to be used

xx = a bit in either PM1A_STS or GPE0_STS

When using V-ACPI both edges of GPIO6 can be sensed. When using the CS5530A, GPIO6 provides additional hardware that

enables the chipset to generate an SMI on both the rising and falling edges of the input signal.
