perform us wait using lptmr driver

[elb1]

Hello i am using lptmr project example from sdk (lptmr_periodic_interrupt) for s32k142, and i want to use for freertos project.
i am not using interrupts which means i don't want it to go to the interrupt once the configured value has past.
What i want is to perform a microsecond delay, how can i do that using the functions that are in lptmr_driver.c file ?

i added this function:

void LPTMR_DRV_DelayUs()

{

    LPTMR_DRV_StartCounter(INST_LPTMR1);

    while (!(LPTMR_DRV_GetCompareFlag(INST_LPTMR1)));

    LPTMR_DRV_ClearCompareFlag(INST_LPTMR1);

    LPTMR_DRV_StopCounter(INST_LPTMR1);

}

so when i first initilize the driver i do this:

    lptmr_config_t lpTmr1_config0 =

    {

        .workMode = LPTMR_WORKMODE_TIMER,

        .dmaRequest = false,

        .interruptEnable = false,

        .freeRun = false,

        .compareValue = 100,

        .counterUnits = LPTMR_COUNTER_UNITS_MICROSECONDS,

        .clockSelect = LPTMR_CLOCKSOURCE_SIRCDIV2,

        .prescaler = LPTMR_PRESCALE_2,

        .bypassPrescaler = false,

        .pinSelect = LPTMR_PINSELECT_TRGMUX,

        .pinPolarity = LPTMR_PINPOLARITY_RISING,

    };

    LPTMR_DRV_Init(INST_LPTMR1, &lpTmr1_config0, false);

And then during the task running i do this:

        (void)gpio_write(&gpio, false);

        LPTMR_DRV_DelayUs();

        (void)gpio_write(&gpio, true);

        LPTMR_DRV_DelayUs();

I was supposed to get 100us delay between the gpio toggling, but instead i get 108us, and the 8 will always be there (ex. if i configure the timer for 50us i will get 58us etc)

Thank you so much for your interest in our products and for using our community.

I noticed that you have another similar case, so I will follow up on this last one that I mention.

Have a nice day!
