In the IRQn_Type structure definition, I only see:
PORTA_IRQn = 30,
PORTC_PORTD_IRQn = 31
on the list.
Does that mean PORTB & PORTE pins are not supported as external interrupts?
Can somebody confirm this?
Unfortunately, only PortA, PortC and PortD support interrupt feature, the PortB and PortE does not support interrupt feature for MKL26Z256.
I copy it here from UM.
Hope it can help you
