I am using TWR K70 , MQX 4.0 and CW 10.5. Normal case i am running from ext 12Mhz oscr at a core frequency of 24Mhz. If my system is idle above 1 min system will switch to 2Mhz and goes to sleep mode ( low power wait mode). When a button press device will wake up at again should run at 24Mhz. But my issue it is hang at PBE mode when wake up from sleep. Can anybody say why this is happening? . My doubt is wheather 12MHz is deisable after low power wait mode. Please let me know your valuable thoughts.
