AM2632: PowerDown question

Part Number: AM2632
Other Parts Discussed in Thread: TCAN1043A-Q1

 Hello, I'm trying to powerdown my module, my assumption ->is that powerdown should be instant. But after execution of the following, it takes additional more 10 seconds. What can be wrong?

   1 - TSTSW_Module_disableAllModules();

   2-  PeriodicTasks_suspend();

   3 -  HwiP_disable();

   4 -  BSP_CAN_enterSleepMode();

   5 - GPIO_pinWriteLow(gpioBaseAddr, pin);

   6 -  vPortEndScheduler();
    portSUPPRESS_TICKS_AND_SLEEP();

1 and 2 necessary to disable periodic tasks

3 need for HwiP disabling

4 put to sleep mode CAN transceiver

5 make low pin which is responsible for power supply
