RM42L432: Using the RTI Compare units as simple timers

Hi,

I am trying to use the RTI compare units as simple timers I can use to block execution in my applications. The flow I would like is:

1. Reset the compare unit so the time it blocks is accurate
2. Wait until the compare has elapsed
3. continue execution with my program

Right now the units are set to use counter0 which is free running in the background. I have made this snippet but it does not seem to work (compare0 is set to 1uS and compare1 is set to 10ms via HalCoGen):

#include "sys_common.h"
#include "rti.h"

uint32_t micros = 0;

int main(void)
{
    rtiInit();
    _enable_IRQ();

    // Enable RTI Stuff and start the timer
    rtiEnableNotification(rtiNOTIFICATION_COMPARE0);
    rtiStartCounter(rtiCOUNTER_BLOCK0);

    uint32_t s = micros;

    rtiREG1->INTFLAG = rtiNOTIFICATION_COMPARE1; // Clear
    rtiREG1->SETINTENA = rtiNOTIFICATION_COMPARE1; // Enable

    while(rtiREG1->INTFLAG & 0x02 == 0) {} // Wait

    rtiREG1->CLEARINTENA = rtiNOTIFICATION_COMPARE1; // Disable

    uint32_t d = micros - s;

    // Example 1s wait with COMPARE0 ISR
    while(micros < 1000000) {}

    return 0;
}

// RTI ISR
void rtiNotification(uint32_t notification)
{
    // Compare 0 is a 1uS period
    if( rtiNOTIFICATION_COMPARE0 == notification )
    {
        micros += RTI_UDCP0_CONFIGVALUE / 10;
    }
}

I am not sure of a few things:

1. Why does the INTFLAG register not transition to 1 for the COMPARE1 bit after the programmed time (d is only 1).
2. What do I need to do to reset the compare to get a full period?

Thanks,

Nathan
