Plug and Play Isolation Sequence
DM9008
ISA/Plug & Play Super Ethernet Contoller
The Plug and Play isolation sequence is divided into four states: Wait for Key, Sleep, Isolation, and Config states. The state transitions
for the Plug and Play ISA card are shown below:
Notes:
1. CSN = Card Select Number.
2. RSTDRV causes a state transition from the current state to Wait for Key and sets all CSNs to zero.
3. The Wait for Key command causes a state transition from the current state to Wait for Key.
4. The Reset CSN commands include PnP Reset, CSN and DM Reset CSN commands.
The former sets all CSNs of ISA PnP cards to zero, while the latter only sets CSNs of DM9008 PnP cards to zero.
Neither command will cause a state transition.
