Part Number: CC1312R

So based on the CC13xx/CC26xx Hardware Configuration and PCB Design Considerations, SET_CCFG_MODE_CONF_XOSC_CAP_MOD is applicable for the SCLK_HF. Is there a similar cap-array for the low frequency clock, or is the only method of changing the capacitance done by switching out the external ones?

  • As stated in the application note, there is no internal loading for the 32 kHz crystal. You have to properly dimension the external capacitors for your crystal and layout.
