How do you set up a keyboard interruption to the PTA1 and PTA3 pins?

Thank you.

Should I add this? Thank you. 

SIM->SCGC |= SIM_SCGC_KBI0_MASK;

KBI0->PE |= KBI_PE_KBIPE_MASK;

KBI0->ES |= KBI_ES_KBEDG_MASK;

KBI0->SC |= KBI_SC_KBMOD_MASK;

NVIC_EnableIRQ(KBI0_IRQn);

Hello carlesls,

Thanks for your post. 

Regarding how to configure PTA1 and PTA3 as KBI Pins, you can use the pin tool of the MCUXpresso Configuration Tool to complete it. For specific operations, you can refer to the attached video recording.

For more configuration questions, you can refer to the following web pages. I believe they will be very helpful.
