Advanced Configuration and Power Interface Specification A.11.1.3 IDE Channel Devices State Status Definition D0 Required Adapter is functional. Adapter interface mode (for example, communications timings) is programmed. Power is applied to the bus (and all devices connected to it). D1 N/A This state is not defined for the IDE Channel. D2 N/A This state is not defined for the IDE Channel. D3 Required Adapter is non-functional. Adapter interface mode (for example, communications timings) is not preserved. Power to the bus (and all devices connected to it) may be off. A.11.2 Power Management Policy A.11.2.1 Hard Disk, Floppy Disk, CD-ROM and IDE/ATAPI Removable Storage Devices Present State Next State Cause D3 D0 Device usage (high-priority I/O). D0 D1* Device inactivity (no high-priority I/O) for some period of time (T1). D0 D3 Device inactivity (no high-priority I/O) for a period of time (T2=>T1). System enters sleeping state. D1* D0 Device usage (High-priority I/O). Note: * If supported. Note: For ATA, the D3-to-D0 transition requires a reset of the IDE channel. This means that both devices on a channel must be placed into D3 at the same time. A.11.2.2 IDE Channel Devices Present State Next State Cause D3 D0 Any device on the channel needing to transition to a state other than state D3. D0 D3 All devices on the channel in state D3. A.11.3 Wake Events Storage devices with removable media can, optionally, signal wake upon insertion of media using their bus-specific notification mechanism. There are no other wake events defined for Storage devices. A.11.4 Minimum Power Capabilities A hard disk, CD-ROM or IDE/ATAPI removable storage device conforming to this specification must support the D0 and D3 states. Support for the D1 state is optional. 964 April, 2015 Version 6.0
A floppy disk and IDE channel device conforming to this specification must support the D0 and D3 states. Version 6.0 965
