AWR2243: HostIRQ, Interrupt triggered at Falling Edge or Rising Edge

Tim Teuber

Part Number: AWR2243

Hi Team,

my Question is pretty much the title of this question. Does my Host-MCU need to generate a Interrupt when AWR2243 pulls the HostIRQ low (Falling Edge), or when it goes back up (Rising Edge)

Thanks,

Tim

    Hi Tim,

    Generally, interrupt is generated during rising edge and then interrupt is served but if you want to know some specific interrupt, can you mention the name of interrupt?

    Hi Animesh,

    Thank you, i am talking about the HostIRQ Signal, from my understanding this is a Active Low Signal. The AWR pulls it low, whenever there is a Asynchronous Message, that the AWR wants to send to my Host MCU. Am I correct about this?

    Thats why i thought the Interrupt should be triggered when HostIRQ falling Edge occurs.

    Also, your question suggest, that there are more Interrupts than HostIRQ, what are those?

    Thanks,

    Tim

    HI Tim,

    you are right, this interrupt is generated at falling edge. you can further read it from mmWave-Radar-Interface-Control.pdf document.
