Using core timer

You can enable core timer functionality in MCC, which will generate code and give you these 2 functions:

	CORETIMER_DelayMs(delay_ms);		//uint32_t

	CORETIMER_DelayUs(delay_us);		//uint32_t

Here’s an example of the code it generates for them

void CORETIMER_DelayMs ( uint32_t delay_ms)
{
    uint32_t startCount, endCount;

    /* Calculate the end count for the given delay */
    endCount=(CORE_TIMER_FREQUENCY / 1000U) * delay_ms;

    startCount=_CP0_GET_COUNT();
    while((_CP0_GET_COUNT() - startCount) < endCount)
    {
        /* Wait for compare match */
    }
}

void CORETIMER_DelayUs ( uint32_t delay_us)
{
    uint32_t startCount, endCount;

    /* Calculate the end count for the given delay */
    endCount=(CORE_TIMER_FREQUENCY / 1000000U) * delay_us;

    startCount=_CP0_GET_COUNT();
    while((_CP0_GET_COUNT() - startCount) < endCount)
    {
        /* Wait for compare match */
    }
}
