AM625: OSPI_INTn connection and usage

Tony Tang

Part Number: AM625

What is the usage of OSPI_INTn? 

When will it trigger interrupt?

It connect to AM62x OSPI_CSn, is it configured as GPIO interrupt source?

What will do to this OSPI_INTn interrupt?

Can it be left unconnected?

    Hello Tony,

    So I have done my research and found out that OSPI_INTn is the OSPI Interrupt Controller.

    So there are two modes to transfer data as per the Datasheet and MCU PLUS SDK drivers guide. I have attached a snapshot below, kindly check.

    So the OSPI_INT pin can be used to signal completion of the transferred data.

    Tony Tang said:

    From the above connection we can see that OSPI_CSN0 can be used as a chip select line to the OSPI flash part.

    But, OSPI_CSN2 can be used to signal the completion of data transfer via Interrupt.

    I hope this explanation helps.

    Looking forward to your response.

    Regards,
