DEVTRAP_EN— Device Trap Enable Register
I/O Address:
Default Value
Lockable:
Power Well:
This register enables the individual trap ranges to generate an SMI# when the corresponding status
bit in the DEVACT_STS register is set. When a range is enabled, I/O cycles associated with that
range will not be forwarded to LPC or IDE.
