dm8168 bios时钟设置

我用的是dvr_rdk4.03,我看到在swms里面有bios时钟的设置

Clock_Params_init(&clockParams);
clockParams.period = xx;
clockParams.arg = (UArg) pObj;pObj->timer = Clock_create(AutoChMpLink_drvTimerCb,clockParams.period, &clockParams, NULL);

UTILS_assert(pObj->timer != NULL);

Clock_setPeriod(pObj->timer, xx);
Clock_setTimeout(pObj->timer, xx);

如果我要设置时钟为continuous模式，定时间隔为3，那么改怎么设置呢？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？
