Interrupts in Synergy

Hey all, 

Gotta be a stupid thing but I cannot get an interrupt to go to the ISR.  Here's the short version:

1. ADC14 on S3DK.  Using the input the Pot is connected to.  Using AD framework, no RTOS.
2. AD function works in single scan or continuous.  Plan is to do continuous.
3. I get AD callback OK and conversion is good.
4. Setting up Window compare function.  Not supported by framework.  Just Channel 13 (the pot) comparing with Window A, arbitrary values of 2000 and 7000.
5. If I check the window compare status bit after AD complete, it indeed works.  I turn on an LED based on inside the window or out.  All is well.
6. Now try to generate interrupt from window compare.  Followed instructions in section section 39.3.5.2 of S3 manual.  I get nada.
7. Interrupts enabled in ICU.  ISR names are same as weak defined names.  Still nothing.
8. It is NOT going to the default ISR routine, so this is good.

Here is code.  I can post project if desired.  General question:  Is there a set of instructions or something for setting up an interrupt when it's not part of the configurator?

Specific question: How do I get the interrupt to do something.

void hal_entry(void) {

    /* Calculate the delay in terms of bsp_delay_units */

    const uint32_t delay = bsp_delay_units/freq_in_hz;

    /* Get LED information for this board */

    R_BSP_LedsGet(&leds);

    /* If this board has no LEDs then trap here */

    if (0 == leds.led_count)

    {

        while(1);   // There are no LEDs on this board

    }

    // setup the ADC14 to convert channel 13 per the Synergy Configurator

    // Ch 13 is the one with the pot on the S3DK over by the display

    err = g_adc0.p_api->open(g_adc0.p_ctrl, g_adc0.p_cfg);

    err = g_adc0.p_api->scanCfg(g_adc0.p_ctrl, g_adc0.p_channel_cfg);

    // the following is per the instructions in the User Manual, section 39.3.5.2

    // now setup the window compare A function

    R_S14ADC->ADCMPDR0 = 2000;        // set the lower level.  Just an arbitrary value

    R_S14ADC->ADCMPDR1 = 7000;        // set the upper level.  Just an arbitrary value

    R_S14ADC->ADCMPANSR0 = 0;               // make sure all other channels are off

    R_S14ADC->ADCMPANSR0_b.CMPCHA13 = 1;    // now make window A look at channel 13

    R_S14ADC->ADCMPLR0_b.CMPLCHA13 = 1;     // trigger if ADCMPDR0 < AD ch 13 < ADCMPDR1

    // disable window b

    R_S14ADC->ADWINLLB = 0;             // disable window for b by setting both upper and lower to 0

    R_S14ADC->ADWINULB = 0;             // disable window for b by setting both upper and lower to 0

    R_S14ADC->ADCMPBNSR_b.CMPCHB = 0x3f;

    R_S14ADC->ADCMPCR_b.CMPAB = 00;     // output on a match with either window A or window B

    R_S14ADC->ADCMPCR_b.CMPAE = 1;      // enable window a

    R_S14ADC->ADCMPCR_b.CMPBE = 1;      // enable window b  // seems odd but per the instructions

    R_S14ADC->ADCMPCR_b.CMPBIE = 1;     // disable interrupt on b

    R_S14ADC->ADCMPCR_b.CMPAIE = 1;     // interrupt on window a

    R_S14ADC->ADCMPANSR1 = 0;               // don't look at the upper channels

    R_S14ADC->ADCMPANSER = 0;               // exclude the temperature sensor and the internal voltage reference

    R_S14ADC->ADCSR_b.ADST = 0;

    R_S14ADC->ADCMPCR_b.WCMPE = 1;      // enable window a

    while(1)

    {

        /* toggle the LED */

        g_ioport.p_api->pinWrite(leds.p_leds[0], (level = !level));

        ad_done = 0;

        err = g_adc0.p_api->scanStart(g_adc0.p_ctrl);       // start the A/D - single scan mode

        while(ad_done == 0);

        err = g_adc0.p_api->read(g_adc0.p_ctrl, ADC_REG_CHANNEL_13, &my_result);        // get the result

        //

        //

        //

        // This all works, just no interrupt for window compare function.

        //

        //

        //

        // turn the pot and the LED goes on at the right time and off at the right time.

        // if the conditions are met, turn on the LED.  If not, turn it off.

        if(R_S14ADC->ADCMPSR0_b.CMPSTCHA13 == 1){

            err = g_ioport.p_api->pinWrite(leds.p_leds[2], IOPORT_LEVEL_HIGH);

            R_S14ADC->ADCMPSR0_b.CMPSTCHA13 = 0;            // clear the bit that says we got a match.

        }

        else{

            err = g_ioport.p_api->pinWrite(leds.p_leds[2], IOPORT_LEVEL_LOW);     // use this LED to indicate A/D done

            R_S14ADC->ADCMPSR0_b.CMPSTCHA13 = 0;            // clear the bit that says we got a match.

        }

    }

}

//// this callback works fine...

void adc14_callback(adc_callback_args_t *p_args)

    ad_done = 1;

}

//////  we never get to either of these.
