Wake-up from LLS using a non-LLWU pin

[javervalino]

Hello all,

I just want to know if its possible for a KL15 mcu to wakeup from lls using a non-llwu pin. In our case we use PTA4 (a NMI pin) as an interrupt source, this supposed to wakeup the unit from lls.

Thank you very much.

Regards,

Javer

Hi Javier,

According to the KL15 Reference Manual on Chapter 3.4.4.2, the microcontroller can wakeup using the NMI when the pin is enabled and asserted

Remember that the NMI pin must be selected in the PORTA_PCR4 mux and the NMI interrupt enabled in the FOPT register.
