NO PORTB or PORTE IRQ handler in KL26/KL16?

[abhishekvishwak]

As per the KL26/KL16 series reference Manual, there are no IRQ handlers for PORT B and PORT E. 

But PORT A is available (irq 30) and Port C and Port D are available on One ISR (irq 31). 

I want to have PORT B and PORT E also to be used as Interrupt pins but they are unavailable to generate an ISFR bit set when they are configured as (PCR Reg using  PORT_SetPinInterruptConfig()).

Is this to say there are no Hardware module present internal to chip responsible for these ports Interrupt. ( ISFR are available but they are going to be useless) there is no hardware detection for when these port pins are asserted?

Also, is there a way to configure them at all on KL chips? As also software interrupts are also not available on KL chips/

Please Advise.

Thank you

Abhi

Hi Abhishek:

Yes, you are right. KL26 only supports external interrupt for PORTA,PORTC and PORTD.  No hardware support for interrupt IRQ PORTB and PORTE.
