Charging management chip settings issue regarding sf32l52

Where can I find the usage example program for the built-in charging management module of sf32l52? I didn’t find any related examples under sdk/example.

I only found the following content in pmu.md and the official SDK programming guide:

void config_charger(void)
{
PMU_ChgCalParamTypeDef cal_param;
uint32_t current;
uint32_t volt;

//config calibration data for charger, calibration is saved in EFUSE  
//cal_param.cc_mn = xxx;  
//cal_param.cc_mp = xxx;  
//cal_param.bg = xxx;  
//cal_param.cv_vctrl = xxx;  
//cal_param.rep_vctrl = xxx;  
status = HAL_PMU_ChgInit(&pmu_chg_handle, &cal_param);  

// config CC current  
current = 300; //300mA  
current = HAL_PMU_ChgConfigCcCurrent(&pmu_chg_handle, current);  

// config target voltage  
volt = 4300;  //4300mV  
volt = HAL_PMU_ChgConfigTargetVolt(&pmu_chg_handle, volt);  

// enable IRQ and register callback  
HAL_PMU_ChgRegisterCallback(&pmu_chg_handle, pmu_chg_callback);  
status = HAL_PMU_ChgConfigIRQ(&pmu_chg_handle, PMU_CHG_IRQ_VBUS_RDY, PMU_CHG_IRQ_TRIG_MODE_DOUBLE_EDGE);  
RT_ASSERT(HAL_OK == status);  
status = HAL_PMU_ChgConfigIRQ(&pmu_chg_handle, PMU_CHG_IRQ_VBAT_HIGH, PMU_CHG_IRQ_TRIG_MODE_POS_EDGE);  
RT_ASSERT(HAL_OK == status);  
status = HAL_PMU_ChgConfigIRQ(&pmu_chg_handle, PMU_CHG_IRQ_EOC, PMU_CHG_IRQ_TRIG_MODE_POS_EDGE);  
RT_ASSERT(HAL_OK == status);  

HAL_NVIC_SetPriority(PMUC_IRQn, 5, 0);  
HAL_NVIC_EnableIRQ(PMUC_IRQn);      

}

Can this code be used directly? Could you please provide a complete official example program for battery voltage configuration?

Additionally, we noticed that this configuration includes settings for full-charge voltage and charging current. Could you please provide the available setting ranges for these two parameters? Can any value within the range be set, or are they limited to specific steps?

Either voltage or constant current charging within the specification range is acceptable; the actual values should refer to the battery’s datasheet.
For usage of the HAL interface, refer to the code in customer\\peripherals\\charger\\sifli_charge\\sifli_charge.c, which encapsulates the charger device interface—namely, the device interface defined in customer\\peripherals\\charger\\charger.h. It is recommended to use the device interface for easier switching between different charging ICs.
