KL26Z Port B interrupt

[d4712]

I notice that PORT B has a Interrupt status register(PORTB_ISRFR) and Control register (PORTB_PCR)

Does it have a interrupt vector?

Hi d4712,

KL26's PORT B does not support interrupt, so it does not have an interrupt vector either.

Yes it does, you can find it (and the other vectors) in the startup_,,,  file (I'm not sure what the full name is for the KL26Z) in the "startup" folder (it should be the only file in the folder.  

As a default, all the interrupt vectors are given the address of a simple handler that clears the interrupt request flags and return.  This handler is defined as a "weak" method that you can easily replace simply by defining a new handler.  

Take a look at one of the example apps in the SDK to see how you can create your own handler.
