cc1310睡眠功能,事件触发唤醒

Other Parts Discussed in Thread: CC1310

我在使用CC1310低功耗时,task()中使用Semaphore_pend(Semaphore_handle(&low_power_sem), BIOS_WAIT_FOREVER)进行等待进入standby状态,在外中断的callback()中使用Semaphore_post(Semaphore_handle(&low_power_sem))唤醒CC1310,但通过仪器测量时,发现CC1310在standby状态时,会周期性(几百ms)的出现电流波动,感觉系统在不停的唤醒检测low_power_sem。请问一下,有什么办法能消除此周期唤醒动作吗?
