* port:
|
|
||||||
* - <b>Init</b>. This state is represented by the startup code and the

|
||||||
* initialization code before @p chSysInit() is executed. It has not a

|

* special hardware state associated.
|
|

|
|

* @p chSysInit(). Interrupts are enabled.
|
|
||||||
* - <b>Suspended</b>. Interrupts are disabled.
|
|
||||||
* - <b>Disabled</b>. Interrupts are enabled. This state is equivalent to the
|
|
||||||
* Suspended state because there are no fast interrupts in this architecture.
|
|
||||||
* - <b>Sleep</b>. This state is entered with the execution of the specific
|
|
||||||
* instruction @p <b>sleep</b>.
|
|
||||||
* - <b>S-Locked</b>. Interrupts are disabled.
|
|
||||||
* - <b>I-Locked</b>. This state is equivalent to the SRI state, the
|
|
||||||
* @p chSysLockI() and @p chSysUnlockI() APIs do nothing (still use them in
|
|
||||||
* order to formally change state because this may change).
