This is the interrupt event object associated with SGIs #29 and #30 (timer and watchdog timer interrupts). It is also what allows GetSystemTick, SleepThread, [[KTimers]], etc. to work.

This is the interrupt event object associated with SGIs #29 and #30 (timer and watchdog timer interrupts). It keeps tracks of the system uptime and manages [[KTimeableInterrupts]].

The interrupt handler of this object updates its counter attributes and returns 0 if it was called with interuptID = 31 (or any invalid interruptID value) (Watchdog timer underflow), otherwise it does nothing and returns the object itself (timer interrupt).

| [[KTimeableInterruptEvent]]

| Instance of a dummy subclass of [[KTimeableInterruptEvent]] used to keep track of [[KTimeableInterruptEvent|KTimerInterruptEvents]] and [[KTimeableInterruptEvent|KThreadInterruptEvent]] of suspended threads

| Instance of a subclass of [[KTimeableInterruptEvent]] used to keep track of all instances of [[KTimeableInterruptEvent]].

Also keeps tracks of the system uptime in CPU ticks, this is updated each time a [[KTimeableInterruptEvent]] is added to its list
