S32K146 clock initilization

Hello EveryOne,

I configure the clock module and use clockMan1 HAL function to initilization, I do not know what is the difference between CLOCK_SYS_Init() and CLOCK_DRV_Init()? if use CLOCK_DRV_Init(), whether have any matter? thanks

Response prom the apps team.

Briefly explain for your concern as my understood is

The difference between CLOCK_SYS_Init() and CLOCK_DRV_Init()? if use CLOCK_DRV_Init()?

CLOCK_SYS_Init – will combine with CLOCK_SYS_UpdateConfiguration to do init the clock and those provide a callback mechanism to inform the result of the init process.

CLOCK_SYS_UpdateConfiguration – could use to switch configuration in case the g_clockManConfigsArr from clockMan1 contain more than 1 set of it

CLOCK_DRV_Init – simply do init the clock without any notification sending back to the driver.

Both of them could use the g_clockManConfigsArr from clockMan1, but in difference manner I suppose you recognize it.

Best regards
