What is the power consumption of the FX2LP18 when held in reset for both the three different supply inputs? I am working on a very power sensitive design and the USB will only be needed when powered externally. When in battery mode, I want to minimize the power consumption as much as possible by holding the part in reset (or even adding a power switch if necessary). The datasheet shows Isusp current, but it is not clear which power rail that is referring to. Also, it's not necessarily the same as when the part is in reset.
