By default, WKUP_LFOSC0 and HFOSC1 are disabled, while WKUP_HFOSC0 is enabled after PORz.
Program CTRLMMR_WKUP_LFXOSC_CTRL register to enable WKUP_LFOSC0 oscillator. CTRLMMR_WKUP_LFXOSC_TRIM[18-16] I_MULT requires configuration based upon the load capacitance of the low-frequency crystal circuit.
All device oscillators with external crystals support a bypass mode. In this mode, an external clock can be driven on the XI Pin.
