Hi~

1838.attach

Like the picture above
In order to use the event trigger using an external pin
I'll use the event_detector & event_generator app in xmc1300 boot kit

But the app is only available until four.
Is there any other way to use more external interrupt??

Hello,

An ERU module supports the generation of 4 interrupts based on input sources (e.g. pins).
Can your application use the built-in OR logic to group 2 pins per ERU interrupt?

Another alternative would be to use other unused peripherals to operate like an ERU.
For example, the DX2T interrupt from the USIC channel in SSC slave mode, which can be triggered depending on the configured trigger edge selected by DX2CR.CM bit field.

Regards,
Min Wei
