TRF7970a TX Complete Flag in IRQ Register

Other Parts Discussed in Thread: TRF7970A

Dear Ti Team,

We have a question about the TX Complete Flag in TRF7970a IRQ Register,

If we read the Irq register while Transmit operation is in progress, will the TX flag be set again at the end of the TX operation?

Thanks and best Regards 

Dietrich

    Hey Dietrich,

    The TX Complete flag is set while the TRF79xx is transmitting.  The Actual IRQ signal does not fire until all data has be transmitted.  

    If you read the IRQ status register before the IRQ has fired, this will not reset the TX complete flag, and the IRQ will still fire.  

    Let me know if you have any more questions.

    Thanks,

    JD
