I'm using a KL14, and cannot seem to get the LPTMR to clock properly from the LPO. I get a single interrupt when the LPTMR is first configured, but never again. I can change the LPTMR clock source to the MCGIRCLK and the interrupt will trigger every time, all the other settings being the same. I'm not using any of the super low power modes, just normal WAIT mode. Has anyone ever seen this issue or have an explanation for it? Thanks.
