I've searched the forums and checked various application notes already, yet I'm struggling to exit the VLLSx mode when I am using an external pin as the wakeup source. According to AN4503.pdf:
"For LLS, VLLS3, VLLS2, VLLS1, and VLLS0 the wake-up events are limited to the enabled LLWU wake-up pins and
modules. The pin can be a wake-up source as long as the pin is enabled as a digital source in the Pin Control Register."
I'm doing this yet I fail to exit the VLLSx mode. I have tried the example "Low-power demo" in the kl25sc with not 100% success. I can enter the VLLSx modes no problem. It's only after I attempt to use the associated LLWU pin (say, PTC3 / LLWU7 ) that I have absolutely no response. I have also tried other LLWUx pins without success.
As an example, please let me know if you can:
1) Enter VLLS1 when an I/O pin goes low (say PTD6 / LLWU15 or PTC3 / LLWU7).
2) Exit VLLS1 when that same I/O pin goes high
This request is for the FRDM-KL25Z Rev. D board.
Help is appreciated! Thanks in advance,
