请教： CC2541進不了低功耗，pwrmgr_task_state 一直为2

可以進到下面的低功耗管理模块中

void osal_pwrmgr_powerconserve( void )
{
  uint32       next;
  halIntState_t intState;
  // Should we even look into power conservation
  if ( pwrmgr_attribute.pwrmgr_device != PWRMGR_ALWAYS_ON )
  {
// Are all tasks in agreement to conserve
if ( pwrmgr_attribute.pwrmgr_task_state == 0 )    //这里一直是pwrmgr_task_state=2
{
   // Hold off interrupts.
   HAL_ENTER_CRITICAL_SECTION( intState );

   // Get next time-out
   next = osal_next_timeout();

   // Re-enable interrupts.
   HAL_EXIT_CRITICAL_SECTION( intState );
   // Put the processor into sleep mode
   OSAL_SET_CPU_INTO_SLEEP( next );
}
  }
}
