CC2642R: Comparator A Sensor Controller Studio

Hi,

I tried to create an example just with the COMPA and the COMPA event trigger. To do that a linked the COMPA to the DIO30. DIO30 is an ADC powered with 3.3V. My trigger is set to occurs when the DIO30 falling edge. 

This is my code:

Initialization Code

state.exec = 1;

// Enable COMPA
compaEnable(COMPA_PWRMODE_ACTIVE);

// Select COMPA reference GND PIN and input
//its works with COMPA_REF_ADC_REF, COMPA_REF_DCOUPL and VSS
compaSelectIntRef(COMPA_REF_VSS);
compaSelectGpioInput(AUXIO_A_ADC_DIO_30);

// Wait for the COMPA output to settle
fwDelayUs(10);

compaGetOutput(output.compaValue);

// Setup the first event trigger, on high level
//0: eventIndex 0:falling edge
evhSetupCompaTrigger(0, 0, EVH_COMPA_TRIG_ON_EDGE);

Execution Code

compaGetOutput(output.compaValue);

Event Handler A Code

state.exec = 3;

// Check the COMPA output
// The comparator output value, 0 if low, 1 if high
compaGetOutput(output.compaValue);

// Setup the next event trigger, on low level
evhSetupCompaTrigger(0, 0, EVH_COMPA_TRIG_ON_EDGE);

Termination Code

// The currently enabled event trigger must be cancelled manually
evhCancelTrigger(0);

// Disable COMPA
compaDisable();

In the Task Testing I can see the compaValue changing but the variable state.exec never changes to 3 (it seems that the event never happens). 

What I'm missing?

I tried with the Sensor Controller Studio: Version 2.6.0.132 (simplelink_cc13x2_26x2_sdk_3_40_00_02) and 2.9.0.208 (simplelink_cc13xx_cc26xx_sdk_6_10_00_29).

Thanks in advance.
