MTK 6260 ISINK2 接LED（正极接VBAT，ISINK接LED负极），操作哪些寄存器，可以点亮...

sfbirihw

handle = DclPMU_Open(DCL_PMU, FLAGS_NONE);

PMU_CTRL_ISINK_SET_EN sink_en;

        sink_en.isink =ISINK2;
        sink_en.enable = 1;
        DclPMU_Control(handle, ISINK_SET_EN, (DCL_CTRL_DATA_T *)&sink_en);
DclPMU_Close(handle);

如上代码，没有效果！
