After reading AUTOSAR_TPS_SoftwareComponentTemplate, I'm still confused about both types of InterRunnableVariable and concepts of data consistency. There are my question:

  1. What is the difference between ExplicitInterRunnableVariable and ImplicitRunnableVariable?
  2. Can InterRunnableVariable be processed by another RunnableEntity from a different software component?
  3. Can AUTOSAR's software component read or write directly to the RAM with given spesific address?
  4. What is the condition where we have to use ExclusiveArea?

  1. 参考：TPS_SWCT_01054 和 TPS_SWCT_01055

  2. 参考：TPS_SWCT_01592

  3. 软件组件是用 C 编写的，而 C（众所周知）为您提供了足够的绳索来吊死自己。问题不是他们是否可以，而是他们是否应该（在正式建模之外）。

  4. 没有条件，专属区域只是代表一种相互排斥的机制。如果您需要实现互斥并且不想使用可运行的变量，请使用独占区域。
