　Aliyun How to set access control RAM If you purchased multiple instances of the cloud server ECS, there are multiple users in your organization who need to use these instances. If these users share the use of your cloud account key, the following issues exist: Your key is shared by more than one person, the risk of leakage is high; You cannot limit the access rights of users, which can cause security risks due to misoperation. Access Control

Introduction: The following method applies only to the small (-ms) and banked (-MB) memory model, not to the large (-ML) memory model. At the same time, Freescale recommended less than 32k code using small, greater than 32k code using banked, is not recommended to use large. RAM: There are two methods of using banked RAM: 1. Use the Local address 2. Use global address (greater addressing) First look at the
