PWM in LLS mode on a FRDM-KL26 board

Question asked by Florian Ackermann on Feb 23, 2015

Hi Guys,


I am trying to implement a low power application and therefore I'm using the LPTMR to switch between RUN mode and LLS mode. The problem is, that during the LLS mode, the tpm for the pwm is not operational and the pwm turns off. I can see at the oscilloscope that the pwm is turned off during LLS. Also when executing the code, the led is blinking. It is supposed to run all the time, though..


I've attached an example project that shows the problem.


Does anyone know how to solve this problem? Any help is greatly appreciated!
