1. Switching Current High specifications are not relevant to PME#, SERR#, or INTA#, which are open drain
2. Maximum current requirements will be met as drivers pull beyond the first step voltage (AC drive point).
3. This parameter is also applicable to CardBus environment.
4. Do not test. Guranteed by design.
