MSPM0L1306: GPIO Interrupt

Kenley

Part Number: MSPM0L1306

Hi team,

There are three possible events: "CPU_INT", "Gen_Event0", and "Gen_Event1".

"CPU_INT" is used for interruptions and when flagged, the subroutine (INT_GROUP1) is executed.

  1. For "Gen_Event0" and "Gen_Event1", there is an interrupt destination like "CPU_INT",  and is it correct that the specified subroutine is executed when the flag is raised?

  2. Customer also would like to know about the behavior of "Gen_Event0" and "Gen_Event1" when executed.

Thank you in advance.

Best regards,

Kenley

    Hi Kenley, 

    1. For the event fabric, there is no ISR or a memory destination to point to like with a CPU interrupt. The event fabric is just a signaling pathway from one peripheral to another. For example, one timer event could trigger a DMA transfer. So, there is no routine to be executed from an event and the CPU does not need to intervene to start this process.

    2. Could you clarify what you are looking for here? You can read more about the general event system in section 6.1 of the MSPM0 L-Series Technical Reference Manual

    Please let me know if you have more specific questions about the event system that I can address. 

    Best,

    Alex
