TMS570 Interrupt Notifications

Pritesh Gudge

Other Parts Discussed in Thread: HALCOGEN

Hi,

The code generated by Halcogen always has interrupts and the respective notification functions.

In this case, when a notification function is called from the ISR, are the interrupts re-enabled or the interrupts remain disabled during the run of notification function. I need to know this to decide how much code to place in the Notification function or just to set a flag which is interpreted by the main loop.

Regards,

Pritesh

    Pritesh,

    Thank you for using our forum.

    During execution of the notification routine for a given interrupt request, the interrupt remains disable at the CPU level (for IRQ).
    It is wise to have your notification routine as short as possible to avoid latency on any other pending interrupt.
