MKE02Z16VLC4 XTAL PIN

AnangBohra — Fri, 16 Dec 2016 05:53:34 GMT

Hi,

I am working on a very simple project where I am reading inputs on nearly all the pins of the micro controller MKE02Z16VLC4 and sending the data over to serial port.

I am also not using any external clock source and the problem I am having is reading the input from XTAL pin.

I have disabled external crystal oscillator and configured the pin as input like all other pins. However, this pin always report HIGH no matter what i do. What am I missing?

I am using KDS and Processor expert.

Thanks

Anang

Hi Anang,

I have help you create a project based on KDS and PE.

When I connect PTB6, XTAL pin to GND, the GPIO PDIR according bit(bit 15) =0

When I connect PTB6, XTAL pin to 3.3V or 5V, the GPIO PDIR according bit(bit 15) =1

So, the XTAL pin is working.

Please refer to my attached code.

Wish it helps you!

Have a great day,
Kerry
