GPIO in L-series

Markon — Tue, 17 Sep 2013 09:23:38 GMT

Hi,

I'm preparing project with MKL16Z64VLH4 and I have questions:

1. May I activate interrupt on every port A, B, C, D, E?

2. May I wake up processor with the use of external pin (for instance PTC6) and than use this pin as external interrupt?

Hi, Mar Kon

Q1. May I activate interrupt on every port A, B, C, D, E?

A1: No, Kinetis L series does not support all ports interrupt.

Q2. May I wake up processor with the use of external pin (for instance PTC6) and than use this pin as external interrupt?

A2: You can reference chapter "Interrupt channel assignments" in reference manual. There is a table which tell you which port can support GPIO interrupt and which port can only support single interrupt.

Hope my reply can help you.

Best Regards

Paul

Thank you for your answer.

May I ask you about reference manual for MKL16Z64VLH4 because there isn't any connected with this processor on freescale webside?
