SceSystimerId sceKernelSysTimerAllocForDriver(SceSystimerType type);

SceSystimerForDriver_0450933B

Version	NID
3.65	0x0450933B

Edit some bits (mask 0xFFF00700) of the timer's config register. Timer must not be counting.

// if (a2 < 0x10), written to bits 0x00F00000
// else (a2 & 0x7) written to bits 0x00000700 and 0x2 written to bits 0x00F00000
// a3 written to bits 0xFF000000
SceInt32 SceSystimerForDriver_0450933B(SceSystimerId timer, SceUInt32 a2, SceUInt32 a3);

SceSystimerForDriver_1B14DFD6

Version	NID
3.65	0x1B14DFD6

Sets the timer's current counter value?

SceInt32 SceSystimerForDriver_1B14DFD6(SceSystimerId timer, SceKernelSysClock a2);

SceSystimerForDriver_59EBD22D

Version	NID
3.65	0x59EBD22D

Start timer.

SceInt32 SceSystimerForDriver_59EBD22D(SceSystimerId timer);

SceSystimerForDriver_7DEBA6A5

Version	NID
3.65	0x7DEBA6A5

Reset timer? Sets current counter and accumulated counter to 0.

SceInt32 SceSystimerForDriver_7DEBA6A5(SceSystimerId timer);

SceSystimerForDriver_8358611F

Version	NID
3.65	0x8358611F

sceKernelSysTimerFree? Stops timer if necessary.

SceInt32 SceSystimerForDriver_8358611F(SceSystimerId timer);

SceSystimerForDriver_85AAE0DD

Version	NID
3.65	0x85AAE0DD

Get timer accumulated time (i.e. *a2 = timer->currentCounter + (sum of counter of each time interrupt was triggered))

SceInt32 SceSystimerForDriver_85AAE0DD(SceSystimerId timer, SceKernelSysClock* a2);

SceSystimerForDriver_904DF737

Version	NID
3.65	0x904DF737

Edits some bits (mask 0x000F0080) of the timer's config register. Timer must not be counting.

// a2 written to bits 0x000F0000
// a3 written to bit  0x00000080
// additionaly, config register is also |= 0x40
SceInt32 SceSystimerForDriver_904DF737(SceSystimerId timer, SceUInt32 a2, SceBool a3);

SceSystimerForDriver_963F7C0D

Version	NID
3.65	0x963F7C0D

Get timer counter (i.e. *a2 = timer->currentCount).

SceInt32 SceSystimerForDriver_963F7C0D(SceSystimerId timer, SceKernelSysClock* a2);

SceSystimerForDriver_A73351C1

Version	NID
3.65	0xA73351C1

Set timer threshold? Timer must not be counting.

SceInt32 SceSystimerForDriver_A73351C1(SceSystimerId timer, SceKernelSysClock a2);

SceSystimerForDriver_BF8D42B0

Version	NID
3.65	0xBF8D42B0

Stop timer.

SceInt32 SceSystimerForDriver_BF8D42B0(SceSystimerId timer);

SceSystimerForDriver_C34D7940

Version	NID
3.65	0xC34D7940

Edits some bits (mask 0x0000F000) of the timer's config register. Timer must not be counting.

// a2 written to bits 0x0000F000
// additionaly, config register is also |= 0x20
SceInt32 SceSystimerForDriver_C34D7940(SceSystimerId timer, SceUInt32 a2);

SceSystimerForDriver_CCCD1EE3

Version	NID
3.65	0xCCCD1EE3

Set behaviour on interrupt.

/*
 * cb will be invoked whenever the timer is interrupted - timer and pUserData arguments will be the same as provided to this function
 * cb will only be called if SceSystimerForDriver_A73351C1() has been called with non-zero argument (e.g. timer has a threshold)
 * cb can be NULL, in which case targetCPU will not be set
 *
 * targetCPU follows the same rules as sceKernelSetIntrTarget() - see SceKernelIntrMgr for more info
 */
SceInt32 SceSystimerForDriver_CCCD1EE3(SceSystimerId timer, SceSystimerCallback cb, SceUInt32 targetCPU, void* pUserData);

SceSystimerForDriver_FD5F1742

Version	NID
3.65	0xFD5F1742

Read some ?counter? from the timer.

SceInt32 SceSystimerForDriver_FD5F1742(SceSystimerId timer, SceKernelSysClock* a2);
