| 0x14
| [[KSendableInterruptEvent]]
| Process termination event
|-
| 0x1C
| u8
| Indicates an ATTACH PROCESS event has been signaled to this object
|-
| 0x1D

| Thread having exclusive access to this object
|-
| 0x2C
| u32
| Debug event flags set by svcContinueDebugEvents
Bit0: no exception dumps are made if this is set.
Bit1 and following: report EXCEPTION (this flag is bypassed for svc 0xFF), SCHEDULE, SYSCALL, MAP debug events, respectively.
