XI is driven by external clock source. XO is pulled down to LOW. Due to ESD
diode to supply, XI should not be driven unless oscillator supply is present.
Note
User should set CTRLMMR_WKUP_LFXOSC_TRIM[18:16] i_mult = 3b’001 for CL in the range 6pf to
9.5pf. CTRLMMR_WKUP_LFXOSC_TRIM [18:16] i_mult = 3b’010 for CL in the range 8.5pf to 12pf.
Default setting is 3b’010.
Note
The load capacitors, Cf1 and Cf2 in Figure 6-35, should be chosen such that the below equation is
satisfied. CL in the equation is the load specified by the crystal manufacturer. All discrete components
used to implement the oscillator circuit should be placed as close as possible to the associated
oscillator WKUP_LFOSC0_XI, WKUP_LFOSC0_XO, and VSS pins.
