1. The Low Power Internal Oscillator cannot be disabled and the MCU cannot be placed in suspend or sleep
2. PMU0 requires two system clocks to update the wake-up source flags after waking from suspend mode. The
mode if any wake-up flags are set to 1. Software should clear all wake-up sources after each reset and after
each wake-up from Suspend or Sleep Modes.
wake-up source flags will read 0 during the first two system clocks following the wake from suspend mode.
