CC1310: About 32.768K-kHz RC Oscillator

Part Number: CC1310


Hi Ti:

     I have  a cc1310 module without 32.768k crystall
It makes the sensor controller do not work.
So I need an internal RC oscillator to drive SC to work.
Can TI provide code examples or any suggestions to help me?

    The selection of LF clock is set in the ccfg.c file:

    Look for this section:

    //#####################################
// Clock settings
//#####################################

#ifndef SET_CCFG_MODE_CONF_SCLK_LF_OPTION
// #define SET_CCFG_MODE_CONF_SCLK_LF_OPTION            0x0        // LF clock derived from High Frequency XOSC
// #define SET_CCFG_MODE_CONF_SCLK_LF_OPTION            0x1        // External LF clock
#define SET_CCFG_MODE_CONF_SCLK_LF_OPTION               0x2        // LF XOSC
// #define SET_CCFG_MODE_CONF_SCLK_LF_OPTION            0x3        // LF RCOSC
#endif
