[FAQ15840]MT2503系列充电电流问题
（1）MT2503支持16级充电电流，各级电流大小如chr_CS_VTH数组中描述。
注意红色部分与默认值不同，需要修改。
const DCL_UINT32 chr_CS_VTH[CS_VTH_SIZE]=
{
PMU_CHARGE_CURRENT_1600_00_MA, PMU_CHARGE_CURRENT_1500_00_MA,
PMU_CHARGE_CURRENT_1400_00_MA, PMU_CHARGE_CURRENT_1300_00_MA,
PMU_CHARGE_CURRENT_1200_00_MA, PMU_CHARGE_CURRENT_1100_00_MA,
PMU_CHARGE_CURRENT_1000_00_MA, PMU_CHARGE_CURRENT_900_00_MA,
PMU_CHARGE_CURRENT_800_00_MA, PMU_CHARGE_CURRENT_700_00_MA,
PMU_CHARGE_CURRENT_650_00_MA, PMU_CHARGE_CURRENT_550_00_MA,
PMU_CHARGE_CURRENT_450_00_MA, PMU_CHARGE_CURRENT_300_00_MA,
PMU_CHARGE_CURRENT_200_00_MA, PMU_CHARGE_CURRENT_70_00_MA
};
（2）无法更改USB充电电流大小。
请做如下修改
void bmt_set_chr_current(void) //hal\peripheral\src\bmt_utility.c
{
......
case PW_USB_CHR:
chr_current = CHR_USB_CHARGE_CURRENT;
drv_trace0(TRACE_GROUP_10, BMT_SET_USB_CHARGE_CURRENT_TRC); 
kal_prompt_trace(MOD_BMT, "USB:chr_current= %d",chr_current);
break;
......
}
