MKE15Z256VLH have GPIO interruption?

Jmir — Wed, 10 Mar 2021 17:47:12 GMT

I plan on coming to adopt the MKE15Z256VLH7 ( KE1xZ serie) in a new project due to its expected longevity.

From the analysis of the datasheet I find no reference to interruptions by GPIO. I will have a input of pulses from an encoder that will have to be treated by interruption to calculate speed.Someone confirm me if this chip has interruptions by GPIO?

The KE1xZ and KE1xF parts have both port driven IRQ and DMA capabilities.
It is only the simple KE and KEA series that have only a single IRQ pin for interrupts.

Hi,

The pin interrupt is described in chapter 34.

Have a great day,
