CCS/CC2650MODA: pin interrupt

Part Number: CC2650MODA

Tool/software: Code Composer Studio

I want to interrupt the pin at the fall of the switch.
No interrupt occurs even if the switch is pressed once or twice after startup.
Pressing several times generates an interrupt.
After that, an interrupt occurs whenever you press it.
What causes an interrupt not to occur after startup?
