Ensure that the PCI reset is HIGH during cold start-up (refer to
diagram).
Ensure that the power supply during cold start-up ramps up linearly from 0 V to 3.3 V

In a CardBus application on a Windows OS notebook, the system may momentarily
freeze and EHCIs root hub does not function when EHCI is disabled and enabled again.
The system crashes if the SAF1562 based CardBus is removed and then inserted again.
When the EHCI is enabled again, Windows performs the following sequence:
When the OHCI is disabled, the Memory Space (MS) bit, bit 1 in the PCI Configuration
