请教MSP432E401Y的privileged mode问题？

您可以看一下用户指南内的说明

1.4.1 Processor Mode and Privilege Levels for Software Execution  以及 1.4.2 Stacks

MSP432在reset之后就会进入Thread mode，而后可以通过CONTROL register来设置是否是privileged

Thread mode

Used to execute application software. The processor enters thread mode when it comes out of reset.

Handler mode

Used to handle exceptions. When the processor has finished exception processing, it returns to thread mode.

In thread mode, the CONTROL register (see Figure 1-12) controls whether software execution is privileged or unprivileged. In handler mode, software execution is always privileged.

您好，再请教一下，按文档上说的，MSP432在reset之后，就进入了thread mode,然后可以在control register设置privilege level,但是修改这个control register也需要是privileged mode权限，我是不是只有用SVC指令才能在thread mode环境下进入修改control register?这个SVC指令以前还没接触过，我也是第一次见到配置NVIC寄存器需要 privileged mode 权限，之前调试过MSP432P401,我直接在软件里面就可以配置NVIC寄存器了，并不需要进入privileged mode权限。
