|
|
*Purpose:
|
|
* EH State management declarations. Does target-dependent definitions.
|
|
*
|
|
* Macros defined:
|
|
*
|
|
* GetCurrentState - determines current state (may call function)
|
|
* SetState - sets current state to specified value (may call function)
|
|
*
|
|
* [Internal]
|
|
*
|
|
