摘要
A PXI Express controller may be configured to support at least three different conditions under which the controller may be turned on. If a chassis (e.g. a PXI Express chassis) interfacing with the controller has a power button, the first condition (which may be considered normal operation) may be met when the power button is being pressed at a time auxiliary power is present. When the chassis does not have a power button, the second condition may be met when the power is switched on at a time auxiliary power is present, and the third condition may be met when the power is switched on at a time auxiliary power is not present. A state-machine comprised in the PXI Express controller may be configured to interface with a chipset equally comprised in the PXI Express controller, to perform the control functions required to provide the support for the three different conditions.
