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 );
}
}
}
