sahilmgandhi | 18:6a4db94011d3 | 78 | * |
sahilmgandhi | 18:6a4db94011d3 | 79 | * The sleep manager is a service for ensuring that the device is not put to |
sahilmgandhi | 18:6a4db94011d3 | 80 | * sleep in deeper sleep modes than the system (e.g., peripheral drivers, |
sahilmgandhi | 18:6a4db94011d3 | 81 | * services or the application) allows at any given time. |
sahilmgandhi | 18:6a4db94011d3 | 82 | * |
sahilmgandhi | 18:6a4db94011d3 | 83 | * It is based on the use of lock counting for the individual sleep modes, and |
sahilmgandhi | 18:6a4db94011d3 | 84 | * will put the device to sleep in the shallowest sleep mode that has a non-zero |
sahilmgandhi | 18:6a4db94011d3 | 85 | * lock count. The drivers/services/application can change these counts by use |
sahilmgandhi | 18:6a4db94011d3 | 86 | * of \ref sleepmgr_lock_mode and \ref sleepmgr_unlock_mode. |
sahilmgandhi | 18:6a4db94011d3 | 87 | * Refer to \ref sleepmgr_mode for a list of the sleep modes available for |
sahilmgandhi | 18:6a4db94011d3 | 88 | * locking, and the device datasheet for information on their effect. |
sahilmgandhi | 18:6a4db94011d3 | 89 | * |
