watchdog配置

请问谁静态配置过omapl138的看门狗？
5 ]  P7 F7 c2 [" p7 W//*************** Add watchdog **********************//
var Clock = xdc.useModule("ti.sysbios.knl.Clock");

Timer.timerSettings[1].mode = Timer.Mode_WATCHDOG;
Timer.timerSettings[1].master = true;

var timerParams = new Timer.Params(); //Create a new Timer params struct

timerParams.periodType = Timer.PeriodType_MICROSECS;
timerParams.runMode = Timer.RunMode_ONESHOT;  // specify if one shot or continuous mode
0 _- [  |9 B4 ]; T4 u/ T$ S2 q) y
Program.global.Mywatchdog = Timer.create(1, "&WatchdogOvertime", timerParams);

这样配置后，编译出错，Unsupported mode: 2 is specified for Timer: 1
竟然只支持chain和unchain的。。 请大神指点怎么配置？？？？
