Each bit indicates if the an access has occurred to the corresponding device’s trap
range, or for bits 6:9 if the corresponding PCI interrupt is active. Write 1 to the same
bit position to clear it. This register is used by APM power management software to see
if there has been system activity. The periodic SMI# timer indicates if it is the right
time to read the DEVTRAP_STS register.
