Which timer is used by OSAL/HAL functionality?

What timer is used for OSAL/HAL functionality? (like osal_start_timerEx)

Checked the timers and those are updated from osalTimerUpdate which is called from osalTimeUpdate. That function uses the external ll_McuPrecisionCount which I don't know what uses in the background (probably it's in one of the precompiled libraries since there is no source-code for it).

I need to be sure if timer1,3,4 are usable for my tasks and none of them are used by OSAL/HAL layers like timer 2 (which is BLE reserved).

The OSAL clock is derived from the sleep clock and is based around timer 2. Timers 1, 3, and 4 are all available for use by your application.

HI Willis,

Is that means the "ll_McuPrecisionCount" is still running when the mcu is in PM2 mode ? when mcu wakeup form PM2 mode, tmp = ll_McuPrecisionCount();in void osalTimeUpdate( void ) can also provide a accurate time stamp.

I also want to know whether ll_McuPrecisionCount is still alive in PM2 mode?
