Size : 0x3C bytes
| Offset | Type | Description |
|---|---|---|

| 0x4 | u32 | Reference count |
| 0x8 | u32 | Count of KThreads that sync with this object - number of nodes in the linked list below |
| 0xC | KLinkedListNode* | Pointer to first KLinkedListNode in node list of KThreads that sync with this object |
| 0x10 | KLinkedListNode* | Pointer to last KLinkedListNode in node list of KThreads that sync with this object |
| 0x14 | KTimeableInterruptEvent | Interrupt event (*this) to be used with KTimerAndWDTManager holding its desired time point (relative to the CPU power-on) in CPU ticks (when handling its list of KTimableInterruptEvent instances).
Gets incremented at each interval |
| 0x24 | u8 | Timer is signaled |
| 0x25 | u8 | Timer reset type (one shot, sticky, pulse) |
| 0x26 | u16 | Starting from 11.3.0-36: set to 0 prior to removing the timer from the KTimerAndWDTManager queue, set to 1 just after that. |
