SCPA033 PCI1520 Implementation Guide 7 5 PC Card Interface There are two different modes on the PC Card interface. The first is 16-bit mode which isanalogous to the legacy ISA bus. The second is 32-bit CardBus mode which is very similarto a PCI Bus. The terminal functions for these two modes are mul...

SCPA033 PCI1520 Implementation Guide 13 9 Power Management Considerations 9.1 D3 Wake Information A power management event (PME) is the process by which a PCI or CardBus function canrequest a change of its current power consumption state. Typically, a device uses PME# torequest a change from a power...
