* This is the state engine which drives the card "as such" which in reality

|
|
* State Description
|
|
*
|
|
* IDLE The card is in this state when no channels are configured.
|
|
* This is the state we leave the card in after _attach()
|
|
*
|
|
* INIT The card is being initialized
|
|
*
|
|
* RUNNING The card is running
|
|
*
|
|
* FAULT The card is hosed and being reset
|
|
