Properly slowing down the clock in real time

[BrendanAZ]

Hello, I'm having some troubles changing the clock speed of an iMX RT1060 in real time. I tried following the TEMPMON SDK example to produce a similar result. However, when I call `CLOCK_SetDiv(kCLOCK_AhbDiv, 1);` it seems to cause the board to slow down, then reset. This is not a watchdog or a temperature panic reset from my testing. Here is the code that is the most relevant. Please let me know if you have any questions.

void
temp_warnings()
{
    int temperature = RT106X_SENSOR_Read(false);
    if (tempisr_high == true &&
        (temperature - tempmon_high_alarm_temp_celsius > 0)) {
        printf("Warning: CPU Temperature has exceeded %dC!\r\n"
               "Throttling the CPU clock speed until temperature lowers.\r\n",
               tempmon_high_alarm_temp_celsius);

        CLOCK_SetDiv(kCLOCK_AhbDiv, 1);

        coreFrequency = CLOCK_GetFreq(kCLOCK_AhbClk);
        PRINTF("The chip core frequency is %d Hz. \r\n", coreFrequency);

        tempisr_high = false;
    } else if (tempisr_high == false &&
               (temperature - tempmon_low_alarm_temp_celsius < 0)) {
        printf("CPU Temperature is below %dC.\r\n"
               "CPU clock speed returning to normal.\r\n",
               tempmon_low_alarm_temp_celsius);

        CLOCK_SetDiv(kCLOCK_AhbDiv, 0);

        coreFrequency = CLOCK_GetFreq(kCLOCK_AhbClk);
        PRINTF("The chip core frequency is %d Hz. \r\n", coreFrequency);

        tempisr_high = true;
    }
}
